JEE Main levelSingle correct optionDifficulty 2 of 3o1083

Phenylmagnesium bromide is added to acetone and the mixture is hydrolysed with aqueous $NH X_{4} Cl$ . The product is

A1-phenylpropan-1-ol
B1-phenylpropan-2-ol
Cpropiophenone
D2-phenylpropan-2-ol

Answer: D

C X_{6} H X_{5} X^{-}

adds to the carbonyl carbon of acetone to give

(CH X_{3}) X_{2} C (OMgBr) C X_{6} H X_{5}

, and hydrolysis gives the tertiary alcohol

(CH X_{3}) X_{2} C (OH) C X_{6} H X_{5}

, 2-phenylpropan-2-ol.
