7.7c The Stereospecificity of E2 Reactions Anti periplanar

[@frankieson2676]

This dude is MILES better than the iconic “the organic chemistry tutor”! please take my professors job- you make something complicated into something that just makes simple sense!

[@ChadsPrep]

Thanks for the kind words Frankie! You may also like my new organic chemistry playlist I'm in the middle of (just finished chapter 11). It was greatly requested so I'm using a whiteboard instead of the green screen/powerpoint. Happy Studying! kzbin.info/aero/PLMlqayk59IvrDL0v151TesyTA9-OjVjnQ

holy moly. im reading my textbook super confused and watched this and cleared everything up. I rate this guy!!!!!!

[@ChadsPrep]

Glad you found it helpful, Neal - welcome to the channel!

[@lanakaleel7123]

I am mad at whoever disliked this video. You are my favorite O-chem professor. Ever.

[@ChadsPrep]

Thanks Lana. I feel like I should crack some joke about it probably being my mom or something, but I should probably refrain. Glad you're finding this playlist helpful!

[@ReidEvers]

These are seriously the best O-chem videos I've come across. Bless you Chad

[@ChadsPrep]

Glad you're finding them helpful Reid!

[@daimerizatiomsdf]

It’s midterm week and I’ve seen you more than my family 🫠thanksss

[@ChadsPrep]

Temporary OChem family - Happy Studying!

[@SisayAlemu-t4c]

It's wonderful to be able to connect with you. By the way, I'm from Ethiopia.

[@ChadsPrep]

Greetings from USA and Happy Studying!

[@DevRightms]

Dude !! why do you have so less subscribers and likes? You are one of the best chemistry teachers on groups who explains the topic REALLY WELL I hope that you get more subs in the future :)

[@ChadsPrep]

Thanks Dev Right! And I've been wondering the same thing. Why don't I have more subscribers and likes? I've come to the conclusion that students are intimidated by my good looks...ok maybe they don't like instruction from short, bald guys! 😜

​@@ChadsPrep You're a good man, Chad.

[@ChadsPrep]

@@dr.apollo4226 Thank you!

[@ravindrakaur2787]

Your explanation methods are outstanding.... thanks for making such useful videos

[@ChadsPrep]

You're very welcome Ravindra and glad you're finding my videos helpful!

[@C-G585]

Quick refresher before my exam. Thanks boss!

[@ChadsPrep]

You're welcome - Hope you do well on your exam!

[@skylardean4540]

Incredible, this video is covered this topic perfectly.,

[@ChadsPrep]

[@nyomimorris6364]

How is the product E at 5:39 if is on the same side shouldnt it be Z like in the example at 4:03?

[@Arjungupta-st6lm]

YOU ARE AMAZING

[@ChadsPrep]

Thank You!

[@ALVINJOSOEPH48]

Hey Chad @5:06 how is the benzene ring and propyl trans to each other ? Thank you for your videos by the way very helpful !

[@ChadsPrep]

Look at where they are attached to the alkene in the product. They are oriented 180 degrees from each other which makes them trans. If you were to compare the methyl and the benzene instead you can see that they are only 60 degrees apart which would make them cis to each other. Thought comparing and contrasting might help. Hope this helps!

[@NavneetKumar-oe7hh]

But for deutorium

[@prodyumna2826]

Thank you Sir...In chair conformer of cyclohexane,are anti defined wrt alpha and ß position, or wrt axial and equatorial position?

[@ChadsPrep]

Both Maa. To be anti-periplanar the halogen on the alpha carbon and the hydrogen on the beta carbon have to be trans-diaxial. So this means that have to be trans, not cis, and both be in the axial positions rather than equatorial positions. Hope this helps!

[@IshratParveen-to1xv]

You are great 👍

[@ChadsPrep]

Thank you! 😃

[@dreameyez8521]

I like this! Do you do thermo?

[@ChadsPrep]

Hello Ashley! They are not on youtube currently but you can find them all conveniently organized (and free) on my site here: www.chadsprep.com/chads-elementary-physical-chemistry-videos/ Happy Studying!

[@dom6783]

Hey Chad! At 1:36 are you saying that the first diagram you drew all the way on the left is anti-periplanar or anti-coplanar? Thanks. My OChem Exam is tomorrow.

[@ChadsPrep]

Hello Dominick. When the H and Br are exactly 180 degrees apart they are anticoplanar. But it turns out that they don't need to be exactly 180 degrees apart for the E2 reaction to occur, just pretty close to 180 degrees. So the newer term to describe being "close to 180 degrees apart" is antiperiplanar. Hope this helps and best tomorrow!

[@strugglingcollegestudent]

They still call it anti coplanar in my class lol

[@user-gd6gv7cr6j]
