Vedclass · Answer

(C) The reaction of benzaldehyde $(C_{6}H_{5}CHO)$ with a Grignard reagent $(RMgX)$ followed by acid hydrolysis yields a secondary alcohol.To obtain $1-$phenylethanol $(C_{6}H_{5}CH(OH)CH_{3})$,the Grignard reagent must provide the methyl group $(CH_{3})$.Therefore,the reaction is:$C_{6}H_{5}CHO + CH_{3}MgBr \rightarrow [C_{6}H_{5}CH(CH_{3})OMgBr]$$[C_{6}H_{5}CH(CH_{3})OMgBr] + H_{2}O/H^{+} \rightarrow C_{6}H_{5}CH(OH)CH_{3} + Mg(OH)Br$Thus,benzaldehyde reacts with $CH_{3}MgBr$ to produce $1-$phenylethanol.

Which of the following is reacted with benzaldehyde to obtain $1-$phenylethanol?
