I put all of my questions/solutions in the attached file...could someone please check over them before 7:00 am to see if I have them correct? Thanks in advance!
Bonus is wrong. There are 2 chiral centers and neither is near enough to the amine to cause racemization. The amine is not a chiral center.
3- and 4-vinylcyclohexanethiol each have 2 chiral centers.
e) is wrong since Br2 adds anti to double bonds, not randomly. You need to make models to see it maybe.
