E2 (Elimination) Mechanism and Antiperiplanar Explained!

- Опубліковано 30 вер 2024
- Hi there! In this video, I go through an in-depth discussion of the E2 (elimination 2) mechanism, its properties, and the ever-confusing topic of antiperiplanar! Organic chemistry can be a real daunting topic, and I hope this video makes it a bit easier!
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!
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.
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.
You're adorable
Haha thank you so much! I hope you found the video helpful!
THANK YOU omggg
My pleasure! I’m so glad you found the video helpful. Best of luck in your course!
OMG THIS WAS PERFECT THANK YOU
Thanks for the video. Way better than my profs explanation.

You just saved my grade ❤️ I was so ready to give up
Aw I am so happy to hear this! Never give up, you got this!
Any chance you have or will go over the relationship between anticoplanar and syncoplanar?
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!
Thanks mate, helped me a lot, even tho im german and couldnt get everything, i think i understood antiperiplanar now
I’m so glad to hear that you found the video helpful! Best of luck in your course
you just saved my life omg
Haha my pleasure! Glad to help!
This video is Really good !
Thanks so much! Sorry for just seeing this comment now haha. Glad you found the video helpful!
helpful video
I’m so happy you found the video helpful! Best of luck in your course
THANK U THANK U THANK U
NO ONE HAS EVERRR EXPLAINED NEWMAN PROJ LIKE THAT
Aw it is my pleasure! I’m so happy you found the video helpful. Best of luck in your course!
man is saving lives and grades, thank you for this!
Aw this comment made my day! Thanks a million! Glad you found it helpful
Awesome video!
Thanks so much! Somehow only seeing this comment now haha. Best of luck in your studies!
No one has explained so good thnx!
Aw thank you so much! I really appreciate that. Best of luck in your course!
You bet I will.

Thanks a lot
MARIAM ALAA my pleasure!
so helpful! thank you!
@ClassicKelly thanks for your comment! I'm so glad you found the video helpful. Best of luck in your course!
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!
@@yakscience4937 ok thanks
Thanks so much for the tip with newmans projection this was exactly what I needed! You're a lifesaver!
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
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!
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!
this helped a LOT for my acs final thank you!!! :)
julia sheehan my pleasure! I’m so happy the videos helped!
Good
Means the world
@@yakscience4937 very good
Sir really really good. Make vedios on more topics to help student like us.
Amazing Work....
Keep it up.....
Thanks so much for your comment! Your support means so much to me.
Fantastic way of teaching... keep up the good work!

amit kumar my pleasure!
Thank you. My ochem 2 final and is tomorrow and I'm reviewing ochem 1 but I never really understood the anti periplanar part
I’m so glad you found the video helpful! Hope you rocked that exam
@@yakscience4937 I aced it!
JT that’s awesome! So happy to hear it
Hey its 5 years after this video came out and this saved me big time
I’m so so glad! Thanks for your comment, and best of luck in your course!
Thank you very much! Clear explanation. :)

Awesome video. Very helpful!
+spencer gibson Glad it helped! Thanks for the comment, and best of luck in your course.
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!
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. Hope this helps!
It does. Thank you!
My pleasure!
You saved me one this concept! Thank you so much
Thanks for your comment! Best of luck in your course
The best explanation on antiperiplanar on UA-cam. Thank youuu ❤
Thanx it helped me alot

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!
Thnks for the wonderful explanation sir !..
The concepts are totally cleared.❤️😄
