Using the valence bond approach, predict the shape and magnetic behaviour of `[CoCl_(4)]^(2-)`.

Text Solution

Verified by Experts

Electronic configuration of Co : [Ar] `4s^(2)3d^(7)`.
Electronic configuration of `Co^(2+) : [Ar] 4s^(0) 3d^(7)`.
`Cl^(-)` does not cause pairing of electrons because it is weak field ligand. Hence,

It has tetrahedral shape and is paramagnetic due to presence of three unpaired electrons.
