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

A

0

B

2.84

C

`4.90`

D

`5.92`

Text Solution

Verified by Experts

The correct Answer is:
A
In `[Cr(CO)_(6)],Cr` is in zero oxidation state
`._(24)Cr=[Ar] 3d^(5)4s^(1)`
As CO is a strong ligand, all the six unpaired electrons will pair up, i.e., there will be no unpaired electron. Hence, `mu=0`
