Hello.
00:03
In this question, we have three compounds to name, three organic compounds, and what we notice in each of these, we see c -o -o -o -h.
00:16
Or in other words, these are all carboxylic acids.
00:27
And this is important to know because that tells us that the end of each of our names is going to end with the suffix owick and acid.
00:39
That is how carbons.
00:40
These are also known as organic acids.
00:45
So let's go ahead and get started.
00:47
We have a benzene ring in letter a with the functional group that makes it a carboxylic acid attached here and then a chlorine attached over here.
01:09
So when we name this, again we know that it's a carboxylic acid, so it's going to end with oic acid.
01:18
So we need to name what is attached to the carboxylic acid.
01:25
So that is a benzene.
01:28
So this becomes benzoic acid.
01:33
But we're not done yet because we still need to name the chlorine group that we see here.
01:46
So if the carboxylic group is attached to the first carbon in the ring, the chlorine is attached to carbon number four.
01:57
In the ring, regardless which way we number going around this ring, it's still going to be on carbon number four.
02:04
So we need to name that also.
02:06
And that is on the fourth carbon.
02:09
So we have to give it an address.
02:12
And then we use the root of its word chloro.
02:19
So what we get is four chloro benzoic acid.
02:23
And that is the correct name of this.
02:27
Four chloro benzoic acid.
02:29
Let's move on to letter b.
02:34
We see, so i am just doing the skeleton structure of these until i get to the functional group so that we can see that it is in fact a functional group.
02:55
Okay, so let's see what we do have here, again, it's a carboxylic acid.
03:02
So it's going to end with oic acid.
03:05
We need to see how many carbons are in the longest continuous chain.
03:09
This doesn't necessarily mean a straight chain.
03:11
We're looking for the longest continuous chain...
