The appropriate reagent for the transformation

A

Zn (Hg)/HCl

B

`NH_(2)-NH_(2)//OH^(-)`

C

Both (A) and (B)

D

None of the above

Text Solution

Verified by Experts

Both Zn(Hg)/HCl and `NH_(2)-NH_(2)//OH^(-)` can reduce `COCH_(3)` group to `CH_(2)-CH_(3)` but HC will also bring about replacement of OH group by Cl. Therefore, the most appropriate reagent is `NH_(2)-NH_(2)//OH^(-)`.
Hence, (B) is the correct answer.
