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

A

zero

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)`
CO is a strong ligand , all the six unpaired electrons will pair up i.e. , there will be no unpaired electron .
`:.pi=0`
