Assertion , `d_(5)` configuration is more stable than `d_(4)`
Reason : `d_(5)` has more exchange energy as compared to `d_(4)` because 10 & 6 exchanges are possible in `d_(5) & d_(4)` respectively.

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.

Text Solution
