Vedclass · Answer

(A) The reaction of a ketone with a Grignard reagent $(R'MgX)$ proceeds via nucleophilic addition to the carbonyl group to form an adduct,which upon acidic hydrolysis yields a tertiary alcohol.$R_2C=O + R'MgX \rightarrow R_2C(R')(OMgX)$$R_2C(R')(OMgX) + H_2O/H^+ \rightarrow R_2C(R')OH + Mg(OH)X$Thus,the product is a $3^o$ alcohol.
