Product of Grignard Reaction with 2-Pentanone

Very Hard Organic Chemistry Carbonyl Chemistry

In organic chemistry, carbonyl compounds exhibit distinct reactions based on their specific functional groups. Among these, aldehydes and ketones can undergo nucleophilic addition, with subsequent reactions leading to various products. Consider the reaction of a carbonyl compound with a Grignard reagent, followed by hydrolysis. What is the main product formed from the reaction of 2-pentanone with methylmagnesium bromide (a Grignard reagent)?

A secondary alcohol with five carbon atoms.

A tertiary alcohol with six carbon atoms.

An aldehyde with six carbon atoms.

A ketone with seven carbon atoms.
