Question

`underset("Ester"(A))(C_(4)H_(8)O_(2))+CH_(3)underset((2"parts"))(MgBr)overset(H_(3)O^(+))rarrunderset("Aalcohol"(B))(C_(4)H_(10)O)`
The alcohol (B) reacts fastest with Luces reaent. The ester (A) and alcohol (B) 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`

Answer 1

Correct Answer - 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.
