In this problem, you're asked to draw structures of compounds given their name.
00:05
So first, we look at 2 -3 dimethyl hexane.
00:09
So hexane tells us that we have six carbons, and at 2 and 3, we have methyl groups.
00:17
So those will be just one carbon attached.
00:21
Then we're asked about 4 -isopropyl, 2, 4 -5 trimethal heptane.
00:26
So, heptane tells us seven carbons.
00:33
At carbon 4 we have an isopropyl group.
00:37
So that's actually this y looking thing.
00:39
So we have three carbons, but they're not in a straight chain.
00:44
And then at carbons 2, 4, and 5, we have methyl groups.
00:58
So then our next structure, we're asked for 4 -4 diethyldecane.
01:05
So deccane tells you you have 10 carbons.
01:13
And at carbon 4, you have two ethyl groups.
01:20
So those are going to be two carbons...
