And there, this question is dealing with functional groups, and we have four answer options.
00:09
So i want to look at the general formula for each of these types of functional groups.
00:15
So first we have esters.
00:18
The general formula for an ester is r, where r represents a hydrocarbon chain of any length.
00:26
And that hydrocarbon chain is bonded to a carbon, which is double bonded to an oxygen, single bonded to another oxygen, and then we have another hydrocarbon chain that may or may not be the same length as the first one.
00:42
So that would be an ester having that general formula.
00:45
Our next one is an aldehyde.
00:51
Aldeides are going to have the general formula where they have a hydrocarbon chain, single bonded to a carbon, and that carbon is double bonded to an oxygen, and then it's bonded to a hydrogen.
01:04
So that would be an aldehyde.
01:06
Letter c are the carboxylic acids.
01:15
The carboxylic acids have a hydrocarbon chain, bonded to the carbon, which is double bonded to an oxygen, single bonded to another oxygen, and then a hydrogen.
01:27
And then finally, we have ketones.
01:34
Ketones are going to have a hydrocarbon chain, bonded to a carbon, double bonded to an oxygen, and then bonded to another hydrocarbon chain.
01:45
Again, it may or may not be the same length as the first one...
