Vedclass · Answer

(D) Benzaldehyde $(C_6H_5CHO)$ reacts with a Grignard reagent $(CH_3MgI)$ to form an addition product,which upon hydrolysis yields $1$-phenylethanol $(C_6H_5CH(OH)CH_3)$.Step $1$: $C_6H_5CHO + CH_3MgI \rightarrow C_6H_5CH(OMgI)CH_3$Step $2$: $C_6H_5CH(OMgI)CH_3 + H_2O \rightarrow C_6H_5CH(OH)CH_3 + Mg(OH)I$Therefore,the correct reagent is methylmagnesium iodide $(CH_3MgI)$,which is formed from methyl iodide and magnesium.
