A

Zn-Hg/HCl

B

Na in liq. `NH_(3)`

C

`NaBH_(4)`

D

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

Text Solution

Verified by Experts

The correct Answer is:
D
Both Zn(Hg) HCl and `NH_(2)-NH_(2)," "OH^(-)` can reduce `COCH_(3)` group to `CH_(2)CH_(3)` group but HCl will also bring about substitution of OH by Cl `therefore` the most effective reagent is `NH_(2)-NH_(2)OH`.
