Question

Assertion: Cu is stronger reducing agent than $H_2$.
Reason: E${}^{\circ }$ of $C{u}^{2+}/Cu$ is negative.

• A. If both assertion and reason are true and reason is the correct explanation of assertion.
• B. If both assertion and reason are true but reason is not the correct explanation of assertion.
• C. If assertion is true but reason is false.
• D. If both assertion and reason are false.

Answer 1

Answer: (D)

$:E^{\circ }$ of $C{u}^{2+}/Cu$ is $+0.34V$ and positive $E^{\circ }$ means that the redox couple is a weaker reducing agent than the $H^{+}/H_2$ couple.
