Okay, so we want to create the following compounds using an intramucular reaction.
00:05
And the first one way of this structure.
00:14
So we can get this by reacting to alcohol with a carboketion because the oxygen on the alcohol is going to attack the carbicotion.
00:22
And we can get a carbocyan from an alkyne reacting with other hbr, hcl.
00:29
So we have one, two, three, four, five, six carbons.
00:37
And carbon six, we've been a primary alcohol.
00:40
Carbon 3 would have been nalkeen attached to the ethyl.
00:46
So reacting with other hcl or hbr.
00:57
We'll get a carbonon, and the oxygen's going to attack it.
01:02
So this is carbon 6, and this is 3.
01:06
They're separated by four carbons.
01:12
So we've still hydrogen here.
01:16
Irvine's going to de -vertinate it.
01:23
We get our products and hbr.
01:33
So for b, we have the strong.
01:39
So we can only create one ring through these reactions.
01:52
So we must have started from benzene.
01:54
And we have a 5 carbon chain attached to one of these carbons.
02:07
1, 2, 3, 4, 5.
02:10
So it's going to be carbon 4 has a methyl attached to it.
02:15
And this is where the carbon caton is going to be.
02:19
So the double bond is going to attack it.
02:25
And we'll get our products.
02:42
Okay, so we've been out keen.
02:44
And if we react this with an alkohelide, so we started from benzene again, then if we had a 5 carbon chain with an aquilite right here, it's going to actually, yeah, it's the 4 carbon chain.
03:12
So if we attack the aquilide, we'll get cycloxane.
03:25
But we can also treat this with nbs and peroxide over heat because we have an allelicabotion.
03:43
So with peroxide, we'll get bromine on the allelic carbon, which could be either here or here...
