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

A

`sqrt(3)`

B

`sqrt(15)`

C

`sqrt(8)`

D

`sqrt(24)`

Text Solution

Verified by Experts

The correct Answer is:
B
In this complex `Co^(2+)` ion have 3 upaired electrons so spin only magnetic moment will be be `sqrt(3 (3 + 3))`, i.e., `sqrt(15) B.M`
