Also agree. 4:45 was best, thank you for telling me that it is only necesary for them in 1plane, in lecture Prof told that reason is about Orbitals, and I thought it was about HOMO/LUMO and stuff that synperiplanar has wrong signs of wavefunction if some Electrons have to move to higherexcited states and stuff. But MO would fit both same-plan, as they just want to be in position to π-bond, but synperi loses to steric reasons.
So i never comment on YT videos but I found this incredibly helpful. I've read my textbook 10 ten times and have watched a bunch of other YT videos regarding E2 mech and this cleared it all up. Thanks a bunch!!
Thanks so much for your comment! This literally made my day! If you're interested, check out my new vlogs on medical school. I appreciate your support!
These videos are so helpful!! I've learned way more from these than my OChem professor. Thank you so much for the precise and organized explanations. The examples really help too! Please make more videos!
Shloka Reddy thanks so much for this amazing comment! This made my day. I am so happy you found the video helpful. Be sure to help me out by sharing my channel with friends!
Janet Spellman thanks so much for your comment! I’m so glad you found it helpful. Be sure to help me out by sharing the channel with friends! Wishing you all the best in your courses and beyond
I never really comment on videos, but I felt the need to make and exception this once since your explanations were beyond good. Thank you very much , I really appreciate it !
Hey Neegarry, thanks for your comment! I'm so glad you found the video helpful. Feel free to check out my new medical school vlog videos! th-cam.com/video/PiXdoTxMc6g/w-d-xo.html
Aw thank you so so much! This made my day. The more sharing the better! My channel could really use the help haha. Be sure to check out my new "Day in the life of a medical student" video! th-cam.com/video/xVFTmpDwozU/w-d-xo.html
Super clear and helpful, thank you so much. One question though: Is it okay to rotate the molecule while its still in the line/skeletal representation instead of putting it in a newmann projection? I tried rotating the molecule to get it anti-periplanar without making the newmann and I seem to have gotten it right. I just don't like drawing those projections haha.
Hey there! I’m so glad you found the video helpful. If you have found an alternative method for finding antiperiplanar arrangement then go for it! I always preferred the Newman projection because it really helps me visually. Be sure to check with your teacher about his/her preferred method for E2 problems, and definitely show him/her your method to make sure it’ll work for all problems. Best of luck in your course!

Hi there! Unfortunately I’ve stopped making chemistry videos since starting medical school, but I’m hoping there are other vids out there explaining it. Best of luck and thanks for checking out my video!
So an E2 reaction will proceed through an antiperiplanar transition state and an E1 reaction will proceed through any of the two (though anti will be preferred) ?
Great question! My understanding is that since E1 starts with carbocation formation, there isn't really a sense of antiperiplanar. This is in contrast to E2, where there is a clear preference for the antiperiplanar arrangement. Hope this helps!
"You kind of look like an idiot but it's fine" LOL. Love this energy, great explanation also, thank you!! Really cool how a video you made 5 years ago is still helping all of us to this day :-)
Aw thank you so much! I’m reading this comment on my break on a really stressful hospital shift, so thanks for making my day brighter! Best of luck in your course :)
i understand the logic behind the new based on how you numbered the carbons but why wouldnt the carbon attacked to the phenyl group be number 1 and the carbon attached 2 the methyl be 2? v confused please help got a test tomorrow!!
Hi there! So I assigned those two numbers totally arbitrarily to make the example clearer (i.e. to make it easier to follow the carbons). Hope this helps!
okay, if i were to give the opposite number of the carbons would the final product turn out the same? and are you always looking down relative to the 1st carbon? Thank you so so much
So let's say, looking at the molecule I drew, I changed the numbers so that the carbon that's attached to the phenyl became carbon 1, and the carbon attached to the methyl became carbon 2. Then, if I followed the same steps and looked down the molecule with the new carbon 1 in front of me and the new carbon 2 behind it, I should get the same product. Please let me know if I understood your question correctly!
Anti - to reduce torsional strain, minimize van der Waals interactions Periplanar - so that p orbitals can overlap to form the pi bond Hope this helps!
Hi Joel. The hydrogen that we plan on removing and the leaving group should be antiperiplanar to each other. These atoms are found in the substrate. So, in order to form our alkene product, we need our substrate to have the leaving group and the hydrogen we wish to remove to be periplanar (and ideally, antiperiplanar) to each other. Hope this helps!
Hi, very good explanation!I am from Brazil and I am looking for a person to talk English to me because I will try PHD in others countries. I saw a opportunity here because we could talk about Chemistry and about life at the university. Best regards!
By far the most helpful explanation of antiperiplanar Newman Projections I've gotten, thank you so much! Better than Khan Academy.
Thank you for your kind words! Totally made my day! I'm so glad you found the videos helpful.
I totally agree with Maddy! Very useful when preparing for my organic chemistry exam.
Thanks so much! Hope you rocked that exam!

Five years later and this is still the best explanation on the internet. Thank you so much.
Thank you so so much! This comment literally made my day! Beat of luck in your course, I'm sure you'll rock it
True, how true. Pittyful that you'll need still long search or luck to find this one-existing good explaining.

Someone knows why X and H need to be antiperiplanar in E2 ?
Anti - to reduce torsional strain, minimize van der Waals interactions
Periplanar - so that p orbitals can overlap to form the pi bond
Hope this helps!
YakScience Thank you so much 😄
What must be antiperiplanar? The substrate or the product?
Hi Joel. The hydrogen that we plan on removing and the leaving group should be antiperiplanar to each other. These atoms are found in the substrate. So, in order to form our alkene product, we need our substrate to have the leaving group and the hydrogen we wish to remove to be periplanar (and ideally, antiperiplanar) to each other.
