Answer

Explanation:

Step1: Identify the longest carbon - chain

The longest carbon - chain contains 7 carbon atoms, so the parent name is heptane.

Step2: Locate the functional group

The hydroxyl group (-OH) is on the second carbon atom, so it is heptan - 2 - ol.

Step3: Identify and number the substituents

There are two methyl groups (CH₃) on the 3rd and 4th carbon atoms and an ethyl group (CH₂CH₃) on the 4th carbon atom. The naming convention is to list the substituents in alphabetical order. So the name is 4 - ethyl - 3,4 - dimethylheptan - 2 - ol.

Answer:

C. 4-ethyl-3,4-dimethylheptan-2-ol
