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.
