So the question asks on treatment with hydrobomine, vinyl cyclohexane undergoes addition and rearrangement to yield one bromo, one ethosyclohexane.
00:10
So using curved arrows, proposed a mechanism.
00:14
So final cyclohexane is going to be this.
00:22
We have a six carbon ring and then a final group.
00:25
And it says hpr.
00:33
So hydrobromic acid is what is it reacting with.
00:38
Since it's an acid, it's going to be a pretty weak nucleophile.
00:41
So the vinyl part of the vinyl cyclohexane, basically the alkene is going to be the nucleophile in which we're using red will attack the hydrogen and then kick off the bromine.
01:00
This is step one in which this will create hydrogen here and then a carbocation here because since it's hydrobomic acid, the.
01:23
With electronic effects and actually steric effects, we want the carbocyan to be the most stable in its most stable form, and it's going to be most stable when it's going to be the most substituted carbon, and the hydrogen is going to go to the least substitute carbon.
01:37
Therefore, we just have a bromine atom, a negative charge, which acts as a great nucleophile to attack this carbocaton, which gives us a product of one bromo, one ethel, chlorhexane...
