The free gaseous `Cr` atom has six unpaired electrons.
Half-filled s-orbital has greater stability.

A

If both assertion and reason are correct and reason is correct explanation for assertion.

B

If both assertion and reason are correct but reason is not correct not correct explanation for assertion.

C

If assertion is correct but reason is incorrect.

D

If both assertion and reason are incorrect.

Text Solution

Verified by Experts

The correct Answer is:
C
(c) Correct reason. All the six orbitals (one 4s and five 3d) are unpaired. Therefore, configuration is symmetrical as well as stable.
