Which of the following is not correctly matched

Options

A. `[Fe(CN)_(6)]^(3-) - d^(2)sp^(3)` and paramagnetic
B. `Fe(CO)_(5)-dsp^(3)` and diamagnetic
C. `[Fe(e n)_(3)]^(3+) - sp^(3)d^(2)` and paramagnetic
D. `[ZnCl_(2)(P PH_(3))_(2)] -sp^(3)` and paramagnetic

Answer

C

Explanation

`Fe(CO)_(5) - Fe(26)= 3d^(6)4s^(2)`
In formation of complex `=3d^(8)` [due to effect of ligand]
hybridisation `=dsp^(3)`, diamagnetic
