Question

the geometry and magnetic behaviour of the complex [Ni(co)4] are

Answer 1

Ni(co)4= Ni+4co
i hope it's help you

Answer 2

Hey dear,

● Answer -
Tetrahedral geometry with diamagnetic behavior

● Solution -
- Electronic configuration of Ni is [Ar] 3d8 4s2
- Unpaired electrons wll get paired as CO is strong field ligand.
- Complex thus gets sp3 hybridization which is responsible for tetrahedral geometry.
- As there are no unpaired electrons, complex behave as diamagnetic material.

Hope this helps you...
