E1 Reaction Mechanism With Alcohol Dehydration & Ring Expansion Problems
ฝัง
- เผยแพร่เมื่อ 29 เม.ย. 2018
- 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!
Thanks sooo much. It really helped. Please upload more like E1,E2,SN1,SN2, Stereoisomer etc.,plssss
I watched 6 ads during the course of this video..... youtube is really pushing it
I know right 😪
thank you for going through major/minor products! my professor rushes through it without explaining and I was so confused.
I was looking for the major and minor products. Surprisingly, I found the hydride and methyl shifts!
I sometimes think what would happened of a person like me if a tutor like you was never there on TH-cam😢❤❤
This dude is simply good at what he does.
A playlist on migratory rearrangements would be a helpful addition.
Sir please upload more videos on organic chemistry
We are very thankful for this...
You're so much better than both of my professors
So many thanks for your great simple educational videos!
Thanks so much🤗🤗
May God bless you😇😇
Very good and understandable video
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
i seriously have a crush on you
awkward...
Ayo 🤔
Pause.
@@shaqaman1862 feel free to attempt this question
Thats like having a crush on ur professor
1:00 is the subproduct a H30 (-) ? cause it loses a proton?
Your voice is awesome......:)
This is so Helpful hehehe😁
When do you use EtOH vs KOtBu/-OtBu?
Thank you
Thank you for the clear explanations! For the last example, can EtOH attack the H on the left side and give the same product?
Yes there is a line of symmetry down the center, so that should give you the same product.
But isn't dehydrohalogenation E2 reaction? Why is it showing E1 mechanism in the video (for that ring expansion question)
I think it's because of the solvent, it's not strong enough for E2
Thaaaank youuuu!!!!
I know this week is busy for you in uploading videos..
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?
what is the difference between E1 and E2 mechanims? Like when do we use E1 and when do we use E2?
Same as Sn1 and Sn2, E1 when steric hinderance is high and E2 when steric hinderance is low.
@@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
PHARMACY STUDENT IS HERE

11:52 "basically" make the double bond..... I see what you did there
I bet that hso4- is too weak base to deprotonate anything
9:00 where did that hydrogen come from?
10:17
1 carbon missing
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?
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
H20 is neutral so it's conjugate base is also weak
Omg so many vids
Really good, but cant say do this question but then introduce new stuff. Get's quite frustrating.
what is the plus icon?
that's your positive charge
I love you
Hello, why does the leaving group leave?
as in e1 carbon becomes bulky and 3 degree carbocation is stable enough so halogen has to leave
@@Moonlight-xl8whkindly don't give false information
If u don't know just shut up and sit down
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)
@@Future_iitian_what's protic I can understand polar but what's polar and non polar protic
@@TheHolyQuran2212 the solvent which has a proton to share is called protic (H+)
