In this question, we have to name each of the given carboxylic acid or ester.
00:11
The first one is the ester.
00:14
The parent carboxylic acid is ch3, ch2, ch2, ch2, cwo, h.
00:21
That h is replaced by the alkali group, methylene.
00:27
And we have this c -o -o, this will represent the ester.
00:34
So we'll start writing methyl and the longest chain containing the c .o .h group in the parent acid contains four carbon atoms.
00:52
One, two, three, four.
00:56
So it will be buta noate.
01:03
Instead of butanoic acid, we're writing buta no -h.
01:09
So it is methide butanoid.
01:13
It is the ester.
01:15
Now, this one is carboaxilic acid because this one has the group cwh.
01:25
And the longest chain containing this carboaxil group has three carbon atoms.
01:32
So the name of this will be propanoic acid.
01:41
What we do here, the name of the alkan is propane with three carbon atoms.
01:48
We cross out the e of the alkan and we write weak space acid...
