The nitrides of alkaline earth metals hydrolyse with water to form:
Correct answer: A. NH3
- A. NH3
- B. H2
- C. N2
- D. NO
Explanation
When alkaline earth metal nitride reacts with water, ammonia (NH3) is produced. The reaction of alkaline earth metal nitrides with water is as follows: M3N2 + 6 H2O → 3 M(OH)2+ 2 NH3, where M is an alkaline earth metal.

About Reactions of Group II Elements
Group II reactions cover the behaviour of beryllium, magnesium, calcium, strontium and barium with water, oxygen, halogens, acids and nitrogen. The trends in reactivity, hydroxide solubility and basicity, along with the thermal decomposition of carbonates and nitrates, depend on increasing atomic size down the group.
