Answer
The substitutents are:
- 1 Ethyl
- 1 Hydroxy
Work Step by Step
1. Identify the parent chain:
In this case, the parent chain will be the horizontal line of carbons on the middle and the carboxylic acid group*.
There are a carboxylic acid and an alcohol, but, since there is only one space for a functional group, and carboxylic acids have higher priority than alcohols, the second one will not be part of the parent chain.
2. Check the atoms, or groups, that are left:
- 1 "-OH"
- 1 Group of 2 carbons.
3. Give them the proper names:
- "-OH" groups are called as "hydroxy" as a substitutents.
- This group of 2 carbons is called "ethyl" as a substitutent.
