Question

Assertion (A): The hydrides of VA group elements are good reducing agents.
Reason (R): $N{H}_3$ is a weak reducing agent among the hydrides of VA group.

• A. Both (A) and (R) are true and (R) is the correct explanation of (A)
• B. Both (A) and (R) are true and (R) is not the correct explanation of (A)
• C. (A) is true and (R) is false
• D. (A) is false but (R) is true

Answer 1

The correct option is B Both (A) and (R) are true and (R) is not the correct explanation of (A)

$N{H}_3$ cannot easily lend hydrogen atom. So it is a weak reducing agent.
Reason does not explain the assertion.
