Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).

Assertion (A) : Cu2+ in water is more stable than Cu+.

Reason (R) : Enthalpy of hydration for Cu2+ is much less than that of Cu+.

In the light of the above statements, choose the correct answer from the options given below :

Multiple Choice Options

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

Step-by-Step Verified Solution

Cu2+ ion is more stable than Cu+ ion due to high charge density on Cu2+ ion, it has higher hydration energy when it bonds to water molecules thus it forms stronger bonds.

∴ (A) is correct but (R) is not correct.
