The spin magnetic moment of cobalt in the compound `Hg[Co(SCN)_(4)]` is

A

`sqrt3`

B

`sqrt8`

C

`sqrt15`

D

`sqrt24`.

Text Solution

Verified by Experts

The correct Answer is:
C
(c) The O.N. of Co in the complex is +2

No. of unpaired electrons (n)=3
Spin magnetic moment `(m_(s))`
`=sqrt(n(n+2))=sqrt(3(3+2))=sqrt(15)`
