MolSynapse / Question bank / Organic Reaction Mechanisms I: Nucleophiles and Carbonyl Addition / Addition of cyanide, bisulphite, Grignard reagents

NEET levelSingle correct optionDifficulty 1 of 3o1115

Acetone reacts with $CH X_{3} MgBr$ in dry ether and the adduct is hydrolysed with dilute acid. The product is

A2-methylpropan-2-ol
Bpropan-2-ol
Cbutan-2-ol
D2-methylpropan-1-ol

Answer: A

Ketones give tertiary alcohols with Grignard reagents.

(CH X_{3}) X_{2} C = O

plus

CH X_{3} X^{-}

gives

(CH X_{3}) X_{3} C - OMgBr

, which on hydrolysis gives

(CH X_{3}) X_{3} C - OH

, 2-methylpropan-2-ol.
