Q43.A metal M on heating in nitrogen gas gives Y . Y on treatment with H2O gives a colourless gas which when passed through CuSO4 solution gives a blue colour. Y is (1) NH3 (2) Mg(NO3)2 (3) Mg3 N2 (4) MgO

What This Question Tests

This question tests knowledge of the reaction of an s-block metal with nitrogen to form a nitride and the subsequent hydrolysis of the nitride to produce ammonia, which gives a characteristic test with CuSO4 solution.

Concepts Tested

Formation of nitridesHydrolysis of nitridesQualitative analysis of ammonia
