Which of the following is not correctly mathced ?

Answer»

`[Fe(CN)_(6)]^(3-) - d^(2)sp^(3)` and paramagnetic
`Fe(CO)_(5)-dsp^(3)` and DIAMAGNETIC
`[Fe(e n)_(3)]^(3+) - sp^(3)d^(2)` and paramagnetic
`[ZnCl_(2)(P PH_(3))_(2)] -sp^(3)` and paramagnetic

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