Ester `A(C_(4)H_(8)O_(2))+underset("(2 parts)")(CH_(3)MgBr)overset(H_(3)O^(+))rarr underset("(alcohol B)")(C_(4)H_(10)O)`
Alcohol B reacts fastest with Lucas reagent. Hence, A and B respectively are

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))_(2)CHOH`

D

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

Text Solution

Verified by Experts

The correct Answer is:
A
Alcohol B is `3^(@)` (reacts fastest with Lucas reagent).
`underset((A))(CH_(3)overset(O)overset(||)COC_(2)H_(5))overset(CH_(3)MgBr)rarr CH_(3)overset(O)overset(||)C CH_(3)overset(CH_(3)MgBr)underset(H_(3)O^(+))rarr underset(B)((CH_(3))_(3)COH)`
