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.

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...

@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 жыл бұрын

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

@raeanne5793 3 жыл бұрын

@@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! (:

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

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

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