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`

Correct Answer - 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)`
