Quizplus · Accepted Answer

In a Grignard reaction, the carbonyl compound reacts with the Grignard reagent to form an alcohol. If a secondary alcohol is desired, the carbonyl group must be a ketone, which has two alkyl groups attached to the carbonyl carbon. The only choice that fits this criteria is an aldehyde (choice B), which has one hydrogen and one alkyl group attached to the carbonyl carbon. The other choices (an ester, formaldehyde, and a primary alcohol) do not have two alkyl groups attached to the carbonyl carbon and therefore will not form a secondary alcohol.
