The spin only magnetic moment value (in ...

The spin only magnetic moment value (in Bohr magneton ) 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
In `Cr(CO)_6` , Cr is in zero oxidation state, `[Ar]3d^5 4s^1`. As CO is a strong ligand, all the six electrons will pair up i.e., there will be no unpaired electron. Hence, u=0.
