Consider the following reaction
`underset("Ester(x)")underset()(C_(4)H_(8)O_(2)) underset("(ii)"H_(3)O^(+))overset((i)CH_(3)MgBr("Excess"))to underset("Alcohol(Y)")underset()(C_(4)H_(10)O)` Alcohol (Y) reacts fastest with Lucas reagent. Therefore (X) and (Y) are

A

(a) `CH_(3)overset(O)overset(||)COC_(2)H_(5),(CH_(3))_(3)COH`

B

`Hoverset(O)overset(||)COC_(3)H_(7),(CH_(3))_(2)CHOH`

C

`CH_(3)overset(O)overset(||)COC_(2)H_(5),(CH_(3))_(3)COH`

D

`Hoverset(O)overset(||)COC_(3)H_(7),(CH_(3))_(2)COH`

Text Solution

Verified by Experts

The correct Answer is:
A
Since the alcohol (B) reacts fastest with Lucas reagent, it is a tertiary alcohol. Ester of formic acid gives only secondary alcohol. Therefore , option (d) is not possible . Hence (a) is the correct answer.
