Calcium Imide on hydrolysis gives gas (2) which on oxidation by bleaching powder gives gas (3). Gas(3) on reaction with magnesium give compound (4) which on hydrolysis gives again gas B. Identify (2), (3) and (4)

A

NH3, N2 and Mg3N2

B

N2, NH3, MgNH

C

N2, N2O5,Mg(NO3)2

D

NH3, NO2, Mg(NO2)2

Answer

NH3, N2 and Mg3N2

Explanation

Solution

Ca(NH) + 2H2O ® Ca(OH)2 + NH3(g)

(2)

2NH3 + 3CaOCl2 ® N2(g) + 3CaCl2

(2) (3) + 3H2O

N2(g) + 3 Mg ® Mg3N2

(3) (4)

Mg3N2 + 6H2O ® 3Mg (OH)2 + 2NH3

(4) (2)
