E2 and E1 Elimination Made Easy! Part 3 ( E1 Mechanism Walkthrough ) - Organic Chemistry
ฝัง
- เผยแพร่เมื่อ 13 ต.ค. 2024
- The last part of my 3 part E2/E1 Mechanism Series! It's the E1 mechanism and also why E1 doesn't care about whether your Beta hydrogens are Anti or Syn. This mechanism is different from E2 because the base is weak and the reaction occurs in 2 steps just like how SN1 is 2 steps and SN2 is 1 step. Hope you guys liked this series! :)

This is the best explanation I've seen for E1 and E2 reactions anywhere (TH-cam, class,etc.), you answered all of my questions, I love how you put both reactions on the board so I can see the difference, you have a great personality.....thanks so much!
please never delete these videos.... i spent the last week distressing and doubting my ability to succeed in ochem because the way these reactions were explained to me was so overwhelming and confusing - but your videos are so clear and they've helped me so much and I'm so thankful I came across them!
You’re very welcome Vivian! 😊 glad they’re still helpful 🙂. Where are you taking OChem at?
I like how you have everything written down and covered with paper, so the video progresses quickly and I don't have to wait for you to draw anything out.
Kali Tempest Thanks!! I'm glad you appreciate them haha. I know they aren't exactly the most aesthetically appealing things.
As other lectures... you showed great ability to teach , thank you.
Golden Falcon Thank you! I really appreciate the support, it's very motivating for me. :] Keep studying hard, and I'll keep making these videos for you. ;)
You, sir, are among the few things I worship.
+Yasmeen Ajaj Haha awhs your too nice. Keep on Orgo-Made-Easy-ing! But anyways not sure if you know but as a subscriber of OrgoMadeEasy you get a lot of perks like access to 2 Weeks Free Yoga and discounts! Check this vid out for all the benefits! ;) th-cam.com/video/1QkGxQCI1es/w-d-xo.html
Your welcome Sherbet! Thanks for taking time out to comment. :] Hope you can actually enjoy Orgo a little now when you do it. haha
Sometimes i like to skip half way through your videos and realise how utterly confused i am at your diagrams, then go back and see them all take form. It's like art.
You're a great teacher, especially for those of us reviewing. You're also incredibly polite which makes me think you are possibly Canadian. Regardless, thank you.
Thank you so much! I have orgo midterm tomorrow didn't understand a thing about Elimination, but your video definitely helped me!
Thanks Taylor! :] Glad I could help! Best of luck w/ Orgo!
You are literally a LIFE SAVER.
before watching ur videos i would stare at the qs blankly, but after ur videos, damn, i can answer them all! God bless u man ^^
That's awesome Emi Stephen !!! Well thanks for watching haha and keep up the hard work. I'm rooting for ya!
For the E2 mechanism products, the product distribution will favor the product with the alkene on the branch (Hofmann product). The bulkier base will favor the product that has the least substituted alkene and vice versa for less bulkier base.
Thank you, these series really helped me to understand what's going on here :) You are good at teaching, keep up the good work!
Thank you so much for making all the wonderful videos. I was ready to shoot myself doing this course online. It's extremely hard being a non-scienece person. But you make it really enjoyable and easy to understand. Thanks again! I believe you'll achieve great things in life!
Deanna Rose Thanks for taking the time to leave a comment Deanna! :D I'm glad my vid could help! Best of luck to you as well!
thank you so mutch i passed my organic test today thanks to you !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Hahaha no problemo Niels Costermans! I'm just to glad to know that I could help :D, are you all done with Orgo now then?
yes its done only have micro biology and analytic chemistry test next week and its over
greetings from belgium !
Such concise and clear instruction! Really helped me out! Thanks and keep it up if you can!
Thanks Christian! ☺️ Still going strong w tutoring but tough to get videos out these days but hopefully that’ll change in September! 😊
U really have helped me man!!!!!!!!!!!! Thanks hope you keep helping us and update us with more Orgo video... :)
Thanks Shrinidhi! I shall tries haha, I've got a few Wittig Reaction videos that I plan on putting up soon. Do you have any topic suggestions? I can't guarantee I will cover them but atleast I know students are struggling with them.
Frank Wong We are generally like coming from a college.......... And i told my friends about your Awesome video.........So Basically We'll discuss the difficult topics and let you know.........Thanks anyway your video has really made it easy xD xD :)
Great video! Theres one essential key information you didn't mention within the 3 part video is Zaitsev's Rule.
No problem dude! Mission Accomplished! haha. Hope you can now see that Orgo actually isn't that bad ;) I can definitely try to make those addition reaction videos. Are they going to be on your exam this friday as well? I already have a summary video for addition reactions on my channel that you can try and look for, it unfortunately doesn't go too far in depth with the individual mechanisms though.
Hi Christian thanks for the comment!
Unfortunately I'm not so familiar with stereoelectric. But I do have a video for isomers(you can search on my channel) if that's what you meant. But I also have to take some time off from making these videos this semester. I've taken up a new position as a Physics Learning Assistant that is taking up most of my time :[.
Ehhh Frankyyyy... Thanks for the help man. Really appreciate it. You've helped me a ton so far in O chem.
+Rachel Elizabeth Hinze Yo yo yo Rachel! Gracias, I really appreciate you really appreciating me because you guys are where I get my inspiration from. :] Here are some Extra Resources for ya! orgomadeeasy.org/extra-resources/
Hi Frank.. Thanks for having the time to upload these very helpful videos, I really appreciate it! You saved me, hopefully I'll pass my Organic chem final exam now, THANKS TO YOU!
THANKS! :D I really want to keep making vids too. But classes and work are really getting to me and I might go cray cray if did videos too lol. But I will start making them again once things slow down for a bit. Keep up the good work and gluck with Orgo!
That's awesome to hear Amber! You're comment made my day haha so thank You! I'm really glad I could help make it easier ;), E2 and E1 were nightmares for me and I always got them confused with SN2 and SN1 haha.
Thanks for this! You made this much easier for me to understand conceptually!
hey frank, im gonna come up to boston some time and give u a big thank you, ur so helpful
Love your videos! They really, really help!
Thanks for the feedback Diba! I really appreciate it :], hope you can enjoy Orgo a little bit more now.
MAY GOD BLESS YOU FOR THIS!!!
You are the best Wong. Thank you very much!
Hahaha thank you for watching and the nice comment. I'm actually planning on curing cancer not rocket science...no jkjk. But seriously I do plan on making more of these videos once I graduate :]. If you can I would really appreciate it if you share this video with your classmates/friends ;).
thank you so much! super helpful in understanding why there is an actual difference! :D
Well doing Frank! Your videos explained many (almost all) of the questions of mine during my lectures! =)
Pui Wai Lee Wooo awesome! Your comment just made my day haha so thanks for that. :D Good luck! #CommentsAreTheBest
Great videos man, you have yourself a new subscriber. Thank you for the help!
Dementis Haha sweet! Thanks for subscribing, and no problem. I'm super glad that i could help. I just checked out your "homework video" lol that's pretty much me 3 years ago when I was studying for Orgo.
Had to rewatch these videos again since i forgot everthing about sub and elim reactions >.< tyvm for saving my life and hope I'll pass the test tmrw so I wont have to watch for the third time xD
Thanking you from a previously confused college student from Ireland (not so confused any more!) :P
You're welcome Michelle! Keep up the not so confused status ;)
love the videos! it would be awesome if you could get a room with a bigger white board though hahaha it can get confusing when so much is going on in a compressed space.
you are so great!!!!! :) this videos have been very helpful!
This part really helpful. Frank would u mind teaching me more about stereoisometric and stereoelectric as well?
Very helpful. Thank you so much!
Your welcome! I'm just glad that I could help :], keep up the hard work!
omg. it's really really awesome:)
thank you so much. u help me a lot:)
Thanks Alice! Your comment is very encouraging and motivating :]. Keep up the hard work.
Thanks! :] I'm glad you found these videos helpful. Go ace any question on E2 and E1 now haha
This was so helpful. Thank you.
Thank goodness I found you; have a test today on this, thanks! :)
Glad you could find me in time! ;) Hope you did well on it.
Haha thanks Mike, discounts when you become a doc sound perfectly fine to me ;).
Thank u sooo much sir... It was really helpful
Mr. Frank Wong, I really enjoy and follow your videos, thank you ! One question though(and might seem like a dumb one), at 2:03, why dont those electrons go to fill up the carbocation spot where Chlorine left?
Fa Al Ah! Good question! So it is actually possible for that to happen as well and in reality that probably happens a percentage of time. But because the base/nucleophile is so big and "hindered" with its 3 methyl groups, it's very difficult to attack that carbon. And the majority of the time the molecule will act as a base and grab the beta-hydrogen which is much more accessible. :]
Okay Thank you, I understand now!
you are awesome frank, thanks you!
this helps so much. Thank you!
Thank you for your videos Frank! I've searched everywhere for a simple break down of the 4 reactions. And all other videos skip the reason/logic behind WHY we are using or applying a specific reaction. This was my weakness when faced with exams. You are doing a great job with simplifying these complex concepts that a lot of Professors and instructors don't start from! (E.g, they go straight into how to get the product and not why we are getting them) Thank you!
Q: Do you know of a chart for the most commonly used compounds for these 4 rxns, and which rxn each of them are mostly used in? I need a complete or informative chart where it shows the common reagents used for each of the 4 rxns. It will be great if you know of one!
Again, thanks Frank!
Thank you SO MUCH!! These helped A LOT! ;)
Great video !
Thanks! Really helpful
Frank, just for clarifications, is the tert-butanol one of the products?? or is it only the HCl??
Thanks for the vid! it really helps :D
more power!
+Chris Alysson Good question! So both are possible inorganic products but usually you just need to worry about the alkene products for elimination. :] Thanks for leaving the comment. Incoming power recieved. ;)
+Frank Wong Awesome! Thanks a lot! The vid helped me a lot for my final examination haha
another dose of power hahaha
keep it up ;)
Hi thanks for explaining SN2, SN1, E2, and E1 reactions so well! I finally understood everything after being confused by my professor for weeks. However I have a question, for the products of E1, will only the first product you drew at 4:16 be formed in the reaction? You also stated the other 2 products (the ones where you said its E2 and E1 products), are they possible products for the reaction or are they the minor products of the reaction? Thanks a bunch!
Hi Frank! When should I indicate the stereochemistry? Btw, the carbocation is sp2 hybridised and it should have a planar shape, why a triangle is used for showing the bond there??
+CHUN KIT AU Great question! The rule is if the carbon is a chiral center then you need to show stereochemistry! I might have made a mistake if it's a sp2 carbon and I showed stereochem so feel free to ignore that. :] By the way have you seen my new video? "7 Must Know Resources For Organic Chemistry" th-cam.com/video/1QkGxQCI1es/w-d-xo.html
you have made my life easier!!! can i just say you look better in an orange hoodie. :D
Absolute legend
Thank you for watching :], hope you can help me by sharing it with your friends/classmates too.
Thank you very helpful :)
correct me if im wrong, but even if there are multiple anti options to choose from, shouldnt we choose the one that will be the most carbon substituted for stability? my professor mentioned this concept very briefly
You are correct!! I currently teach my students that for E1 you just make the most substituted Alkene regardless of Anti or Syn Hs and regardless of base size. Since most E1s are done in heated conditions the most stable product is what will be favored. For E2 however if you use a big bulky base like KOTBu you will be forming the least substituted Alkene product possible via an Anti Beta H.
2013 Frank was mistaken when it came to the E1 part 😅
There are many things 2024 Frank wishes he could’ve been there to tell/teach 2013 Frank when he was making these videos 😆
@@OrgoMadeEasy okay, thank you so much! that clears up a lot. and no, 2013 you did a great job! this video literally saved me 20 pages of textbook reading. thank you again
Haha thank you Tiloya! And your welcome, your so kind. I will do my best to keep at it when I have free time :]. If you ever would like to ask me questions/request a video for a certain topic feel free to contact me via. my channel's Facebook page ;)
You are awesome!!!!
ur a king
Woot Woot Mission Accomplished then! And haha point taken. (P.S. idk why TH-cam didn't send me an email about your comment like they normally do. Hence the late response)
How do you know if the wedges become straight lines when the double bond forms?
Do you have skills in basketball as well?
thanks man
THANK-YOU !!!!
Hey, question. At 4:16, at the right hand side of that double bond, wasn't that supposed to be CH2 since the electrons were moved to form the double bond? Thanks!
Diana Chavez Ah! I think I see your confusion so for the molecule at 4:16 where I have the double bond between the carbons with the 2 Wedged CH3 groups coming off. In order to form that double bond I had to pull off the 1 dashed hydrogen all the way on the left the one at 2:28. Hope that clears it up! :]
^^ like ur video so much:)
I will subscribe to your videos:)
great haircut by the way :)
Haha I wish! (Only have some skill in volleyball :] )
Your* . I'm getting all my Your and You're confused >< sigh*
