Answer
The substitutents are:
- 1 Methyl.
Work Step by Step
1. Identify the parent chain:
In this case, there is one carbon bifurcation with 2 groups of 1 carbon connected to it, so you will have to choose which one you
will pick as a part of the parent chain. (There are no difference.)
And, the "-OH" is the functional group of the parent chain.
2. Check the atoms, or groups, that are left:
- 1 CH3 (The carbon you didn't pick for the parent chain.)
3. Give them the proper names:
- CH3 groups are called by "methyl".
