`[Fe(H_2O)_6 NO]` and `[Cr(NH_3)_6](NO_2)_3` both are paramagnetic species with 'spin' only magnetic moment of 3.93 B.M. The hybridisation of central metal ions in these species respectively are :

A

Both `sp^3d^2`

B

Both `d^2sp^3`

C

`sop^3d^2 and d^2sp^3`

D

`d^2sp^3 and sp^3d^2`

Text Solution

Verified by Experts

The correct Answer is:
C
`3.93=sqrt(n(n+2))`, so n=3 (here n is number of unpaired electrons
