Vedclass · Answer

(D) The target alcohol is $1,1-diphenyl-1-ethanol$ (or $1-phenylethanol$ derivative with two phenyl groups attached to the same carbon). Reaction of a ketone with a Grignard reagent $(RMgX)$ followed by acidic hydrolysis yields a tertiary alcohol. Specifically,the reaction of acetophenone $(Ph-CO-CH_3)$ with one mole of phenyl magnesium bromide $(PhMgBr)$ followed by acidic hydrolysis $(H^+)$ proceeds as follows: $Ph-CO-CH_3 + PhMgBr \rightarrow Ph-C(OMgBr)(Ph)-CH_3$ $Ph-C(OMgBr)(Ph)-CH_3 + H_2O/H^+ \rightarrow Ph-C(OH)(Ph)-CH_3 + Mg(OH)Br$ This matches the structure of the product shown in the image. Therefore,the correct reactant is acetophenone $(Ph-CO-CH_3)$.

Which reactant will give the following alcohol on reaction with one mole of phenyl magnesium bromide $(PhMgBr)$ followed by acidic hydrolysis?
