Vedclass · Answer

(D) $Grignard$ reagent $(RMgX)$ reacts with aldehydes (except formaldehyde) to form secondary alcohols and with ketones to form tertiary alcohols.$R^{-}MgX + CH_3CHO$ $\rightarrow CH_3-CH(OMgX)-R$ $\xrightarrow{H_2O} CH_3-CH(OH)-R$ (Secondary alcohol).$R^{-}MgX + CH_3COCH_3$ $\rightarrow CH_3-C(OMgX)(CH_3)-R$ $\xrightarrow{H_2O} CH_3-C(OH)(CH_3)-R$ (Tertiary alcohol).

Grignard's reagent reacts with ethanal (acetaldehyde) and propanone to give:
