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

`CH_(3)COOC_(2)H_(5)" and "(CH_(3))_(3)COH`

B

`HCOOC_(3)H_(7)" and "(CH_(3))_(2)CHOH`

C

`C_(2)H_(5)COOCH_(3)" and "(C_(2)H_(5))_(3)COH`

D

`HCOOC_(3)H_(7)" and "(CH_(3))_(3)COH.`

Text Solution

Verified by Experts

The correct Answer is:
A
(a) The alcohol is a tertiary alcohol `(CH_(3))_(3)COH` since it reacts fastest with Lucas reagent. `CH_(3)COOC_(2)H_(5)` will form this alcohol. Ester `HCOOC_(3)H_(7)`(d) will not form teritary alcohol. It will give secondary alcohol.
