The geometry, hybridization and magnetic moment of `[Ni(CO)_(4)]` are …. .. And … respectively.

Options

A. tetrahedral, `sp^(3)`, zero
B. aquare planar `sp^(3),sqrt(3)`
C. tetrahedral `sp^(3),2sqrt(2)`
D. square planar `dsp^(2)`. Zero

Answer

A

Explanation

On applying valence bond theory Ni has electronic configuration `[Ar]3d^(8)4s^(2)` and in presence of CO (strong field ligand) electronic configuration is `3d^(10)` Hybridization is `sp^(3)` and all the electrons are paired.
