Question

Which of the following alcohols can be prepared by the reaction of methyl formate with excess Grignard reagent?
Options
A 1-pentanol
B 2-pentanol
C 3-pentanol
Correct Answer
D 2-methyl-2-pentanol
Correct Answer

Option C is the correct answer.

Detailed Explanation

Methyl formate (HCOOCH3) with excess Grignard reagent gives a tertiary alcohol. The structure of the alcohol depends on the Grignard reagent used. For 3-pentanol (which is a secondary alcohol, not tertiary), this would require a specific Grignard. Based on the answer, the Grignard reagent must be ethylmagnesium bromide, giving 3-pentanol.

Hint

What alcohol is formed from methyl formate and excess ethyl Grignard?
