AIIMS 2008 Chemistry Crystal Field Theory Assertion Reason Question

Type: Assertion Reason-conceptual-Medium-Class 12

Assertion: In high spin situation, configuration of d⁴ ions will be t₂g² eₓ². Reason: In high spin situation, pairing energy is less than crystal field energy.

A

Both Assertion and Reason are true and Reason is the correct explanation of Assertion.

B

Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

C

Assertion is true but Reason is false.

D

Both Assertion and Reason are false.

Correct Answer

Option C

Detailed Explanation

In high spin situation, Δo < P, in d^6 configuration, 4th and 5th electron are added to eg rather than t2g. So configuration of d^6 ion will be t2g^4 eg^2
