Ethyl acetate `(CH_(3)COOC_(2)H_(5))` is allowed to react with excess of `CH_(3)MgI` in dry ether and subsequently heated with water. The final product formed is

Options

A. `CH_(3)COC_(2)H_(5)`
B. `CH_(3)COCH_(3)`
C. `(CH_(3))_(3)C-OH`
D. `C_(2)H_(5)-underset(OH)underset(|)(C)(CH_(3))_(2)`

Answer

C

Explanation

Tertiary alcohols containing at least two identical alkyl grouips may be prepared by the reaction between a Grignard reagent (`2` molecules) and any ester (`1`molecul) other than formic ester:


A secondary alcohol is prepared by interaction of a Grignard reagent (`2`molecules) and formic ester (`1` molecule).
