The spin only magnetic of `Cr^(3+)` in aqueous solution would be `:`

A

`sqrt(3) B.M.`

B

`sqrt(15)B.M.`

C

`sqrt(8)B.M.`

D

`sqrt(35)B.M.`

Text Solution

Verified by Experts

The correct Answer is:
3
`._(24)Cr^(3+),3d^(3)` configuration with three unpaired electrons `i.e. n=31`
`:. mu_(B.M.)=sqrt(n(n+2))" ":.mu_(B.M.)" "sqrt(3(3+2))" "sqrt(15)B.M.`
