I don't understand why the alkene would attack the bromine instead of the water. The bromine seems to be in a good, stable, covalent bond while the hydrogen is polar positive. Wouldn't that attract a nucleophile much more? EDIT: I found the answer. The negatively charged pi-bond induces a dipole in the bromine - making it attractive to the nucleophile.
Never ask questions about organic chemistry, as it's never predictable by logic, only by luck. All of this is just based on observation. I'm not talking about your question specifically but the subject in general.
Thanks. I was really troubled in this problem that where to attack the h2o molecule....ie. the less sterically hindered site or site which allows formation of more stable carbocation.
It's based on the resonating structures(r.s.) stability and don't consider a r.s. to be reality of the molecules.Among the two incomplete octet c+ r.s. the one having more stability will contribute more to the hybrid.That's why it attacks the site having more positive charge.
I think the main reason is that a tertiary carbocation would be more stable and hence the positive charge would be localized there, even if in this reaction it isn't a conventional carbocation. Therefore H2O acting as a nucleophile would rather attack there.
idk when you get the cyclic Br+ , it gets opened by the water and not Br-. It bigger and more negatively charged, its supposed to be a better nucleophile right ?

You are a legend in teaching
I had a test on reactions of alkenes and one of the problems was a detailed mechanism of this exact reaction it was hard but i think i did well!
I know it's been months, but I just came across your comment and was curious. If you don't mind my asking, did you indeed do well?
DAMNIT I NEEDED THIS VIDEO LAST QUARTER HAHA
This video was halohydrincredible! 👍
I miss organic chemistry and binge watching these videos
I’m guessing you also miss Heisenberg

Wtf walter
Awesome video.... Plz make a video on beckman rearrangement.
What is that? I am in grade 11
It's in 12th Amines
@@kartik3019 I wish I knew what that is

Very helpful! Thank you!
1:17 Why would it attack the primary carbon?
I am able to understand organic chemistry bex the way you explain it far easy here in indian teachers teaches to make sleep students

@@linxuser897 I agree 💯
pls upload math lectures too related to algebra etc etc , thanking you in anticipation.

4:39 Which one is major product
I saw the same video you teached two years back
Why OH ion even in the presence of Br2 attack on tertiary carbon rather than secondary and primary ??
Please reply
Why can't Br ion attack on tertiary carbon ??
I think the main reason is that a tertiary carbocation would be more stable and hence the positive charge would be localized there, even if in this reaction it isn't a conventional carbocation. Therefore H2O acting as a nucleophile would rather attack there.
Just a doubt. It has classical or non classical carbocation?
What's the electrphile here?😢
idk when you get the cyclic Br+ , it gets opened by the water and not Br-. It bigger and more negatively charged, its supposed to be a better nucleophile right ?
How’d u know I have an exam on Monday??
How'd your exam go?
Luv u JG
From which country you are?
thnks
Suggestion for A video; please make chemistry videos from the syllabus of IIT JAM exam.. One of the toughest exams in India.. Please..
I know it's been years, but I just came across your comment and was curious. Did you take the JAM exam, and if so, how did it go?
Thenks

im freaking crying AGGH
Hey what if it's trans alkene + br2/h20 , will it have meso or racemic mixture
