Hello everyone.
00:01
Today we're doing chapter 19 problem 32 and this problem asks us to rank the following compounds in each of these groups a and b in order of increasing boiling points.
00:09
So what do we know about boiling point? well, the more polar your molecule is, the higher the boiling point is going to be.
00:16
And so how we can determine that is the number of polar atoms or polar atoms on a molecule.
00:25
You can determine that by the number of hydrogen bombings that can form on the molecule.
00:29
So let's look at least.
00:30
At a.
00:30
So if you look at the most left example, we can have a hydrogen bond donor and a hydrogen bond acceptor from these two moieties on this carboxylic acid, one being hydrogen bond donor from the carboxylic oxygen, one being the acceptor from the carbonyl oxygen.
00:49
In the second one, we only have one hydrogen bond donor, and then third one, we also have one hydrogen bomb donor.
00:54
So right off the bat, you can say that this one, having more interactions with other molecules of its own or with water, this is going to have the most highest boiling points because it is the most polar.
01:08
So this is going to be the highest boiling point.
01:13
Now what about these two? well, here we have an ether.
01:16
Here we have an alcohol.
01:17
So this alcohol can be deprotonated to get a full negatively charged oxygen...
