NEET Chemistry (general) Assertion Reason Question

Type: Assertion Reason-assertion-Hard-Class 12

Assertion (A): The E° value for the Cu2+/Cu couple is positive. | Reason (R): The high energy required to transform Cu(s) to Cu2+ (aq) is not balanced by its hydration enthalpy.

A

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

B

Both A and R are true, but R is not the correct explanation of A.

C

A is true, but R is false.

D

A is false.

Correct Answer

Option A

Detailed Explanation

The positive E° value for Cu2+/Cu is due to the high energy needed to transform Cu(s) to Cu2+ (aq), which is not compensated by the hydration enthalpy, as explained in the NCERT context.
