Question

name the following structure.
select the correct answer below:
2 - ethyl - 2 - butanol
3 - methyl - 3 - pentanol
3 - ethyl - 3 - butanol
2 - ethyl - 3 - pentanol

Explanation:

Step1: Determine the parent chain

The parent chain should be the longest carbon chain containing the -OH group. Here, the longest chain has 5 carbon atoms (pentane).

Step2: Locate the substituents and -OH group

The -OH group is on the 3rd carbon. There is a methyl group ($\text{CH}_3$) also on the 3rd carbon.

Step3: Name the compound

According to IUPAC naming rules for alcohols, we name it as 3 - methyl - 3 - pentanol.

Answer:

3 - methyl - 3 - pentanol
