Which of the following reagents react differently with HCHO, `CH_(3)CHO` and `CH_(3)COCH_(3)` ?

A

HCN

B

`NH_2 NH_2`

C

`NH_2OH`

D

`NH_3`

Text Solution

Verified by Experts

The correct Answer is:
D
`NH_3` forms different compounds with the given reagents.
`HCHO+NH_3 rarr underset("tetramine")underset("Hexamethylene")((CH_2)_6N_4)+6H_2O`

`2[CH_3]_2CO+NH_3 rarr underset("Diacetone ammonia")((CH_3)_2C(NH_2)CH_2COCH_3)`.
