When we look at these chains, we need to find the smallest repeating pattern and consider what monomer it could have formed from.
00:14
So for the first one, our monomer is going to be chf, and that's going to have a double bond between those carbons.
00:24
So that double bond is actually where the connection is able to happen.
00:28
So if you take those and put a whole bunch of them together, they bond across that double bond.
00:36
Right.
00:37
For the next one, same kind of idea.
00:40
Our smallest unit this time definitely has oxygen in it.
00:44
Remember, a lot of times if there's an oxygen, that means there's a condensation happening to form that polymer, which means we're going to have some h and some oh on either end of our monomer, because that's what's removed when it becomes a polymer.
01:01
So for this one, we're going to have a carboxylic acid on one end, an alcohol on the other end, and we can see in that polymer that the h and the oh are gone because of that water.
01:19
Right.
01:20
For the next one, it's a little bit more complicated because we have two different repeating patterns here.
01:25
Right.
01:26
So what we see, if we break it apart into two different patterns, again, we have to consider those hydrogen atoms.
01:33
Right.
01:34
So we have a nitrogen chain with some carbon in it.
01:38
So we have nh2, ch2, ch2, th2, nh2 is one.
01:42
And then on the other side, we have another carboxylic acid compound, right? so we have that oh group, ch2, ch2, c -o -h...
