I think at 9:52, we have a primary carbon and a tertiary carbon. Thank you so much for making these videos. They have been saving me.

My professor had to go through multiple examples and I was still confused at the end. I watch your 12 minute videos and understand everything I should know by now. Thanks 🙏🏼

@tomatrix7525 4 года назад

I like the explanations. My teacher just explains this as ‘ok so simply, hydrogen attaches to end breaking the double bond, carbocation in middle, that bonds with negative bromine. Done , easy see...’ and that’s her done...

Do I understand this video? Hell yeah Does my teacher teach to make me understand? NaBro

@sambrailsford3800 6 лет назад

At 9:50 you label a carbon that's connected to three other carbons as secondary carbon. Shouldn't it be a tertiary carbon?

@ethanlittlestone1122 5 лет назад

yes

@janichka95 5 лет назад

@@ethanlittlestone1122 No, double bonds cannot be classified.

@raeanne5793 3 года назад

@shyl venk he did in the example prior..if you "cant consider the carbon attached to double bond", then the last example would only have primary carbocations sooo

@someone-yj2im 3 года назад

@@raeanne5793 So is it actually tertiary carbon or second?? Can you explain?

@raeanne5793 3 года назад

@@someone-yj2im it would be a tertiary carbon, I believe he just made a mistake in the video. It is a tertiary carbon because when the electrons from the double bond attacks the H-Br, that double bond goes away and you are left with two possible carbocations. I think viewing the skeletal structure makes it easier to see this so I linked the google doc I created that shows you. here is the link: docs.google.com/document/d/1QXvka44V0s5bEpC-orfS9ECNug5IbPx2CXonhBiCBzE/edit?usp=sharing Carbocation #1 in the google doc shows that it is a tertiary carbon, and Carbocation #2 is a primary carbon. Let me know if this helped, or if you need it explained differently! (:

@RawDoggin_78 2 года назад

you are my saviour

@britneymack8664 3 года назад

Shouldn't that be a tertiary carbon instead of a secondary carbon in the last example?

@prestonemulala7645 2 года назад

How do you determine the major product for the Alkene where the both carbons in the double bond are secondary carbons.

@sofzhuk1188 3 года назад

ahh yes, here I am again, after attending lecture and reading my book and still not understanding :)

Is there a chiral center on the last example, resulting in racemic enantiomers?

@nourelshabassy8158 5 лет назад

Jaqueline Rios you heard a little wrong; it’s an empty ‘p’ orbital

@eliyahbohadana3172 Год назад

In the second reaction, correct me if I’m wrong but it isn’t you major product because u had to do a hydride shift

@user-fq7ee1bt4l 4 года назад

In last example for HBr, there is 3rd carbonation, and a primary one, there is no 2ndery carbonation in the question, while you keep say 2nd ....

What are the products formed when Bromine Water reacts with 2-methylpropene ?

@NguyenNhan-yk3sr 2 года назад

I think besides the hydrobromination,the alkene also undergo a reaction with the hydroxyl group,forming pentanol as well.

@ArshSahu 6 месяцев назад

When alkene react with bromine water anti addition takes place and it proceeds though cyclic transition state

@strugglingcollegestudent Год назад

6:22 how did you know the structure switched like that

Why doesn't Br ever make a bond that's in the plane of the page: why is it always either dashed or wedged?

@werewolwolf Год назад

Csp3 is planar, the P orbitals are the only ones which can react, so it goes either up or down

@cilened.s1788 5 лет назад

Is that Br going to have and enantiomer since theres a chiral center
