Question

identify the name of the given alcohol.
select the correct answer below:
2 - hexanol
3 - methyl - 4 - pentanol
3 - methyl - 2 - pentanol
1, 3 - dimethyl - 2 - pentanol
2, 3 - dimethyl - 1 - pentanol

Explanation:

Step1: Determine the parent chain

The longest carbon - chain containing the \( -OH \) group has 5 carbon atoms. So, the parent chain is pentanol.

Step2: Number the carbon atoms

Number the carbon atoms in the parent chain such that the \( -OH \) group gets the lowest possible number. Here, the \( -OH \) group is on carbon - 2.

Step3: Identify the substituents

There is a methyl \( (-CH_3) \) group on carbon - 3.

Answer:

3 - methyl - 2 - pentanol
