Spin - only magnetic moment of [Co(NH(3)...

Spin - only magnetic moment of `[Co(NH_(3))_(3)(H_(2)O)_(3)]Cl_(3)(` in Bohr Magnetons ) is `:`

A

Zero

B

`sqrt(3)`

C

`sqrt(24)`

D

`sqrt(35)`

Text Solution

Verified by Experts

The correct Answer is:
1
Oxidation state of `Co` is `+3` in the complex
`E.C.: [Ar]3d^(@),Co^(3+)` is nearly always low-spin
Hence,

Also, `mu=sqrt(n(n+2))=0`
`:' n=`no . Of unpaired electrons `=0`
