The appropriate reagent for the transformation

A

Zn(Hg), HCl

B

`NH_2NH_2OH^(-)`

C

`H_2 // Ni`

D

`NaBH_4`

Text Solution

Verified by Experts

The correct Answer is:
B
Both Zn(Hg), HCl and `NH_2NH_2, OH^(-)` can reduce `-COCH_3` group to `-CH_2 - CH_3` group, but HCl will also bring about dehydration of alcohol to form alkene. Therefore, appropriate reagent for the conversion is `NH_2NH_2, OH^(-)`.
