This question asks us for the stereoisomers that can be obtained from this reaction.
00:05
So here we have this symmetrical alkene reacting with hbr and peroxides.
00:11
And in this case, the peroxides aren't really going to affect where the bromine goes because it is symmetrical.
00:18
These two carbons are the same.
00:20
So if we just draw a generic product here, it will look like this.
00:30
We'll have our ephal groups up here.
00:36
And then the h will go on one carbon, and the bromine will go on the other.
00:41
And we have now created two stereocentors here.
00:45
Both of these carbons are now stereocentors.
00:49
So we have to give all the possible stereosomers from those two.
00:55
So two to the two, two to the n, n is the number of stereo centers, gives us four possible stereosomers...
