From this problem, we're given different reactions, and these are going to involve adding bromine to a structure.
00:09
So our first two are going to deal with nbs as our reagent.
00:17
So with that, our double bond stays intact, but then we add a bromine to one of the carbons that's worn away from our double bond.
00:26
And here, because we have symmetry, it doesn't matter which of those.
00:31
Carbons we choose.
00:33
So with our product, we keep that double bond.
00:37
And then bromine gets added one carbon away from our double bond.
00:43
For the next one, we're going to have a similar process here.
00:47
And we only have one option for where that bromine can go.
00:52
So our double bond stays intact...
