State reason for the following The molecular shape of Ni(CO)_4 is not the same as that of [Ni(CN)_4]^(2-) .

Answer»

Solution :Electronic configuration of:
`NI : [AR] 4s^2, 3d^8`
Ni (O) :`[Ar] 4s^0 , 3d^(10)`

`[Ni(CO)_4` has `sp^3` HYBRIDISATION and has TETRAHEDRAL shape.
`[Ni(CN)_4)_2^(-)`
`Ni^(2+) ,4s^0 3d^8`
