Vedclass · Answer

(B) $1.$ When an excess of Grignard reagent $(PhMgBr)$ reacts with an acid chloride $(CH_3COCl)$,the reaction occurs in two steps.$2.$ Nucleophilic acyl substitution: The first equivalent of $PhMgBr$ reacts with $CH_3COCl$ to form acetophenone $(Ph-C(=O)-CH_3)$ and $MgBrCl$.$3.$ Nucleophilic addition: Since the Grignard reagent is in excess,a second equivalent of $PhMgBr$ attacks the carbonyl group of acetophenone to form an alkoxide intermediate,which upon acid workup $(H^+)$ yields $1,1$-diphenylethanol $(Ph-C(OH)(Ph)-CH_3)$.Reaction:$CH_3COCl + PhMgBr$ $\rightarrow Ph-C(=O)-CH_3$ $\xrightarrow{PhMgBr} Ph-C(OMgBr)(Ph)-CH_3$ $\xrightarrow{H^+} Ph-C(OH)(Ph)-CH_3$.
