The spin only magnetic moment value of `Cr(CO)_(6)` is

A

0

B

2.84

C

4.9

D

5.92

Text Solution

Verified by Experts

The correct Answer is:
A
The chromium is in zero oxidation state having configuration `[Ar]^18 3d^5 4s^1` . The CO is a strong field ligand so compels for the pairing of electrons. Thus the complex has `d^2 sp^3` hybridisation and is diamagnetic.
