This is the answer to chapter 15, problem number 45 from the smith organic chemistry textbook.
00:11
And in this chapter, we are asked to draw the products formed when each alkenes is treated with nbs and light.
00:19
And so remember that nbs and light are going to give us bromination at the allelic position of an alkeen.
00:30
And so for a, since this molecule is a ring, we're really only going to get the one product, since any multiple products would look exactly the same.
00:49
So that's going to be a.
00:52
So then for b, we are going to get bromination at the two possible positions.
01:02
Positions here.
01:04
And so they will look like this.
01:16
So we can get bromination here.
01:23
And then the other potential that we have is for the double bond to rearrange.
01:36
And so we can have the double bond here.
01:42
And so we can have the double bond here.
01:45
And then we'll get bromination.
01:48
At this position because it's an allelic system, so the double bond can move, and we can get promenation at the new allelic position.
02:04
So those are our two options for b.
02:08
So then for c, there are actually going to be four potential products here...
