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)
