The mechanism of the given reaction is to be provided. Concept introduction: Carbonyl groups of esters react with two equivalents of Grignard reagents and followed by hydrolysis to produce tertiary alcohols. The initial product formed between Grignard reagent and carbonyl ester is unstable. This complex structure loses magnesium, bromine, and alkoxide to form a ketone . The ketone is highly reactive with Grignard reagent, compared to esters. The ketone reacts immediately with the remaining Grignard reagent. This intermediate product is hydrolyzed to form tertiary alcohols.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone
