Question

Assertion (A): Ammonia is a reducing agent.

Reason (R): Ammonia reacts with chlorine to liberate nitrogen gas.

Options

• If both A and R are true, and R is the correct explanation of A.

• If both A and R are true, but R is not the correct explanation of A.

• If A is true, but R is false.

• If both A and R are false.

Answer 1

If both A and R are true, and R is the correct explanation of A.

Explanation:

The assertion is true because ammonia acts as a strong reducing agent because nitrogen is in its lowest oxidation state (−3), allowing it to readily donate electrons. The reason is also true and correctly explains this property because when ammonia reacts with chlorine, it reduces the chlorine to chloride while being oxidised itself to liberate free nitrogen gas.
