Question

The theory that can explain the nature of bonding in nico4

Answer 1

Answer:

Valence bond theory.

Explanation:

Ni(CO)4 = Ni + 4CO

The valence shell electronic configuration of ground state Ni atom is 3d8

4s2

.

All of these 10 electrons are pushed into 3d orbitals and get paired up when strong field CO ligands approach Ni atom.

The empty 4s and three 4p orbitals undergo sp3

hybridization and form bonds with CO ligands to give Ni(CO)4

. Thus

Ni(CO)4

is diamagnetic.

Answer 2

Bonding explained by Valence bond theory

Explanation:

To find the shape of complex using valence bond theory there are certain rules :

1.Write the complex formula  that is nickelcarbonyl(II)

2.Remove the electrons from the metal ion as per its valency that is : Ni²⁺.

                                          

3.Rearrange the electrons of metals if necessary as shown below in figure attached .

Hybridisation and overlapping of hybrid orbitals occur
