Okay, so we have got isobutine reacting, hbr, and ether.
00:13
And they were asking us a series of questions about this.
00:16
And i think, to me, the easiest way to go about this is actually to draw the mechanism to give product a, and then the mechanism to give product b first.
00:25
So we're going to do c first.
00:28
So let's follow with c to get product.
00:34
All right, this double bond will swing open to grab a proton and leave an egg.
00:38
Charge on bromine and if we're interested in product b we're going to want to put the carbocatine on a tertiary center right that means adding the hydrogen here and the carboketion here such that when bromine attacks we get a tertiary alcohol halide okay so this is product b now let's do it again but when we add hbr we will add the hydrogen to the tertiary carbon and the carbocadion on the primary side.
01:20
So now we've added our hydrogen here, but a carbocation here, and then we'll have bromine.
01:27
It's negative charge and attack there to give product a.
01:34
Okay...
