In this question, we are naming alkynes.
00:06
So to do that, we're going to, starting with a, we're going to number the longest carbon chain, putting the alkyne at the lowest number that we can.
00:14
So we'll start over here with one, two, three, four, five, six, seven, eight carbons.
00:22
We have a methyl group at carbon six.
00:25
So that goes out in front, six methyl.
00:28
Our alkyne is at carbon two.
00:30
So we have to add that in.
00:31
And then eight carbons is, i'm sorry.
00:33
And then y &e for the alkyne, six methyl two octane.
00:39
B will do the same thing.
00:41
So we'll start with our alkyne, one, two, three, four, five, six, seven.
00:48
We have a couple of substituents here.
00:50
We have a methyl group on carbon four and an ethyl group on carbon five.
00:55
So we'll go in alphabetical order there...
