@@PunmasterSTP not good. I took ochem, physics, calculus, and speech at the same time. I’m sure some people can do that but I’m lazy. Someone convinced me to hurry my curriculum up. I would suggest taking it slow and getting good grades
I would like to personally thank you for helping me out with this difficult part of Alkene reactions! I had a lot of trouble understanding this, previously.
I get to exam time and struggle for a bit before finding a leah4sci to explain the difficult concepts to me like I'm a human being instead of a robot. I have had such a hard time getting professors to explain things like I do not have a phd in chemistry. Like I understand you look at that thing and just know what is what, but I don't feel like I should have to go out of my way to get an explanation of which carbon is which during class. my goodness, thank you. If I ever get into medschool I'm sending you a card.

Leah, you've helped me so much over the last year. Today is the day before the final in ochemII. I was really nervous and was in my professors office today talking about how worried I was. I came home to do my homework and was still so confused. But this video just calmed me down so much. Thank you for the amazing lesson. I never comment but I just really wanted to say thank you! I really appreciate how much work you put in to your channel and website. You are my favorite online Ochem tutor! The way you explain things is always on my level. Thank you a million times.
Though I'm no longer in ochem and I'm only watching these videos as a review, I feel much the same way about Leah! I know it's been years, but I had come across your comment and became curious. If I might ask, how did your final go?
I can't even tell you how helpful this was! Truly, I don't know why my professor doesn't just watch videos on how to explain the concepts better - this was SO helpful!
Such SmoothLy and TechnicaLLy Explained. . . U Just Made this Reaction Mechanism look so Easy. . . THANKZ a Lot. . . Would Love to See Videos on CARBONYL CHEMISTRY Name Reactions from You. . .
As soon as you described this at 7:25 everything clicked!! I've been able to do these cycloadditions but couldn't figure out how to place substituents. Thank you for this!
I just fell in love with you! I have no background in organic chemistry and this Diels Alder reaction was totally over my head until I found your video! It was so good that now I have to find a way to overcome the secretion of oxytocin in my body!!
Hello Teacher your method is very easy I impress your method please help me in organic chemistry more I wish specialization in organic chemistry you tell me you help me????
This was completely insane! I just loved the way you taught thank you so much btw are you having videos on aromatic and anti aromatic compound I really need it ***** mam
The direction of the arrow in the video at time 3:26 is clockwise. If I reverse the direction to counterclockwise but the final product remains the same, does it mean I am representing the mechanism incorrectly (i would love to know)
Great question! For more on the stereochemistry of the Diels Alder reaction, watch my newest video in the series first. th-cam.com/video/Pvu59IJ4vE8/w-d-xo.html
Additionally, why did you break the double bond between C3 & the oxygen group of the dienophile but carried it over into the reaction with the double bond at b?
I did not attach a hydrogen to the oxygen atom. Rather, I drew in the hydrogen of the aldehyde as it is understood to be connected to the carbonyl carbon. If you find you need a refresher on Organic functional groups, make sure to read my Functional Groups Guide at leah4sci.com/functional-groups-guide
I am unsure of which part of the video you are referencing in your second question. Since I don't offer tutoring over social media, to get help with questions like this and more, I recommend joining the organic chemistry study hall. Details: leah4sci.com/join or contact me through my website at leah4sci.com/contact/
why do they call it electron donating and electron withdrawal groups? the electron donating in turn is receiving electrons from the withdrawal group and obviously the withdrawal groups is giving its electron s from its pi bond to the electron donating (diene) group?
I'm sorry, but I don't offer tutoring over TH-cam comments. For more help with this, I recommend joining the orgo study hall. Full details: leah4sci.com/join
When you add heat into a system, you provide enough energy for the molecule to adopt less than favorable conditions including temporarily breaking pi bonds / resonance. During this time the diene can reform into s-cis or s-trans
first of all, she has a lot of knowledge. Obviously. Secondly, what if she learned by some off chance by experimentation? Then her credentials would be the same for those who in earlier years came up with some kind of class or course, taught by some knowledgeable person, (Today's professor) about Chemistry ! One does not have to have some kind of degree in "any" subject to teach it. These are just tutorial courses moron !!
youre literally so good at explaining things, you should be paid a full professors level salary. thank you leah!!!
You're so welcome! I'm glad my videos have helped you!
Anyone else cramming for this uncrammable class like I am? lol...
bro i feel you lol
totally same here😭
I know it's been a while, but I just came across your comment and was curious. How'd the rest of your class go?

I hope it went well! :)
@@Leah4sci It did :) 92
This was completely insane! I just loved the way you taught thank you so much btw are you having videos on aromatic and anti aromatic compound I really need it ***** mam
So glad you liked the video, happy to share! Please see leah4sci.com/syllabus to match up my resources with what you're looking for.
Spent all day reading a book to understand this. Thank you
You're very welcome! I personally always look for a video first, then use the book to fill in any missing details.
Excellent video 👍❤️
Thank you
great video, ty leah
You're very welcome!
you always make sense
Aww thanks! So glad it's helping you!

Hi very nice lecture.
Glad you liked it!
Thanks so much!
you're welcome. :)
Thank you mam!❤
you are very welcome
sounds like there's a ping pong championship going on in the background lol, just kidding, great video!
How do you know there's not ;)
thank you !
You're welcome!
Break make? More like "Beautiful videos that are always great!" 👍
Awww, thanks so much!
Thank you.
You are welcome
The direction of the arrow in the video at time 3:26
is clockwise. If I reverse the direction to counterclockwise but the final product remains the same, does it mean I am representing the mechanism incorrectly (i would love to know)
It's a cyclic mechanism which means the electrons are all moving at the same time. No, it wouldn't be wrong
I just realized today that you share the same name with one of my favorite contributors in Chemlibretexts named Leah Nichols from Butte College(?).
Anyway, I love all your videos, my saviors from org chem. Thank you very much!!
How cool!
You're so welcome! Thanks so much for your kind words!
Omg!!! I can't believed you replied to me!! Thank you mam!! ❤️
Thank you!!!!
You're very welcome
I love you!!!!!!!!!! Thanks
You're welcome! :)
How do you know that your product has stereochemistry and is a racemic mixture?
Great question! For more on the stereochemistry of the Diels Alder reaction, watch my newest video in the series first. th-cam.com/video/Pvu59IJ4vE8/w-d-xo.html
Hello! Thank you for you very informative videos, I love them! I am a little lost @7:49, why did you attach a hydrogen to the oxygen?
Additionally, why did you break the double bond between C3 & the oxygen group of the dienophile but carried it over into the reaction with the double bond at b?
I did not attach a hydrogen to the oxygen atom. Rather, I drew in the hydrogen of the aldehyde as it is understood to be connected to the carbonyl carbon.

you need an award. cover allylic and alkadienes more :)
Too funny! Thank you!
it is helpful
happy to help!
Thx
Yw!
please sir can you help me sir I'm very fearful now how to remember reaction mechanism
Don't focus on remembering. Really learn it and understand why each step happens
Why do we need an s-cis conformation to do the reaction?
For help with this and more, I recommend joining the organic chemistry study hall. Full details: leah4sci.com/join
7:14, how can you just switch the strans diene to s cis?
When you add heat into a system, you provide enough energy for the molecule to adopt less than favorable conditions including temporarily breaking pi bonds / resonance. During this time the diene can reform into s-cis or s-trans
What made you an expert in organic chemistry? What are your credentials? Are you just showing off what little knowledge you have on youtube?
What made you a douche? Is it your upbringing or are you just born like that?
first of all, she has a lot of knowledge. Obviously. Secondly, what if she learned by some off chance by experimentation? Then her credentials would be the same for those who in earlier years came up with some kind of class or course, taught by some knowledgeable person, (Today's professor) about Chemistry !
