E1 Reaction Mechanism With Alcohol Dehydration & Ring Expansion Problems

This organic chemistry video tutorial provides a basic introduction into the E1 reaction mechanism. It includes example problems with carbocation rearrangements such as the hydride shift, methyl shift, and the ring expansion. It discusses E1 elimination reactions of alkyl halides and the E1 dehydration reaction of alcohols using H2SO4.

You're actually the best dude. If I don't understand something about chem, you're the first place I look. Perfect voice for explaining things too! <3

[sarahholland]

thank you for going through major/minor products! my professor rushes through it without explaining and I was so confused.

[munch]

Thanks sooo much. It really helped. Please upload more like E1, E2, SN1, SN2, Stereoisomer etc., plssss

[SuloveKaushik]

I sometimes think what would happened of a person like me if a tutor like you was never there on YouTube😢❤❤

[tommyguir]

I watched 6 ads during the course of this youtube is really pushing it

[mrmusaa]

I was looking for the major and minor products. Surprisingly, I found the hydride and methyl shifts!

[randhirkotwal]

Sir please upload more videos on organic chemistry

[omagaomaga]

This dude is simply good at what he does.

[philpd]

A playlist on migratory rearrangements would be a helpful addition.

7:41 i would like to make a correction - although you got the correct majar product but since you made the cabocation you should had also done the hydride shift from left alpha H . by this you would get a more stable carbocation and 2 alkenes..HOPE YOU WILL DO THE CORRECTION

[theresa.gerges]

what is the difference between E1 and E2 mechanims? Like when do we use E1 and when do we use E2?

[zaminahmed]

You are great dude. I wish all chem professors were like you. A suggestion I would give though is could you make some of the videos a little shorter?

[tlili]

You're so much better than both of my professors

[SophieSong-vfbz]

Thank you for the clear explanations! For the last example, can EtOH attack the H on the left side and give the same product?

[arditehrani]

So many thanks for your great simple educational videos!

[bjswamy]

But isn't dehydrohalogenation E2 reaction? Why is it showing E1 mechanism in the video (for that ring expansion question)

[a.i]

11:52 "basically" make the double I see what you did there

[nostro]

1:00 is the subproduct a H30 (-) ? cause it loses a proton?

[nikodg]

I bet that hso4- is too weak base to deprotonate anything

[randhirkotwal]

I know this week is busy for you in uploading videos..
