Which of the following reacts with water liberating `NH_(3)` ?

A

`Be_(3)N_(2)`

B

`Mg_(3)N_(2)`

C

`Ca_(3)N_(2)`

D

All of these

Text Solution

Verified by Experts

The correct Answer is:
D

`Be_(3)N_(2)` is rather volatile due to the greater tendency of Be to covalency, but other nitrodes are not volatile. All the nitrides are crystalline solids which decompose on heating and ract with water liberating `NH_(3)`
`M_(3)N_(2)+6H_(2)Oto3M(OH)_(2)+2NH_(3)`
