11.4 Show how are the following alcohols prepared by the reaction of a suitable Grignard reagent on methanal?

11.4 In the Grignard reagent reaction, the first step of the reaction is the nucleophilic addition of Grignard reagent to the carbonyl group to form an adduct, Hydrolysis of adduct results in the formation of alcohol.

Here, is the general reaction with Grignard reagent below:-

From here, it is clear t
