Assertion : Cu is stronger reducing agent than H ₂ . Reason : E^ of Cu ²⁺ / Cu is negative.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

D. If both assertion and reason are false.

Step-by-step solution

E^ of Cu ²⁺ / Cu is +0.34 ~V and positive E^ means that the redox couple is a weaker reducing agent than the H ⁺ / H ₂ couple.
