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!

@munch6814 6 лет назад

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

@sarahholland5980 3 года назад

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

@mrmusaa2260 Год назад

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

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

@nostro1940 Год назад

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

@theresa.gerges 2 года назад

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

@xianhezhang3070 2 года назад

Same as Sn1 and Sn2, E1 when steric hinderance is high and E2 when steric hinderance is low.

@Future_iitian_ Год назад

@@xianhezhang3070nooo you are so wrong E1 is used when good leaving group and weak base E2 is used when bad leaving group and strong base attacking

@SophieSong-vf7bz 8 месяцев назад

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

@classicalcole7312 8 месяцев назад

Yes there is a line of symmetry down the center, so that should give you the same product.

@bjswamy3193 5 лет назад

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

@msadjei9147 5 месяцев назад

I think it's because of the solvent, it's not strong enough for E2

@nikodg194 5 лет назад

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

@a.i1137 2 года назад

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

@GG-co2tb 7 месяцев назад

When do you use EtOH vs KOtBu/-OtBu?

@nostro1940 Год назад

10:17 1 carbon missing

@zaminahmed297 3 года назад

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?

@akshanshuanand9493 3 года назад

How is H2O acting like a weak base here? Shouldn't it donate an electron pair to the carbocation and follow Sn1 instead of E1?

@aylora7033 2 года назад

are u saying because the strong acid reacted with the R-OH which is a weak base and donated a proton that H2O+ is now is a conjugate strong acid? H2O+ left as H2O and became a good stable leaving base. besides, Sn1 wouldnt happen because there is heat involved

@Future_iitian_ Год назад

H20 is neutral so it's conjugate base is also weak

@alexia7748 Год назад

Hello, why does the leaving group leave?

@Moonlight-xl8wh Год назад

as in e1 carbon becomes bulky and 3 degree carbocation is stable enough so halogen has to leave

@Future_iitian_ Год назад

@@Moonlight-xl8whkindly don't give false information If u don't know just shut up and sit down

@Future_iitian_ Год назад

Dear Alexia , leaving group leaves because the solvent used is polar protic Polar solvents tends to break the bond which are ionic by dipole dipole interactions If you have any other doubt you can ask me I am from IIT (the institute which you get after giving the toughest exam of world)
