The d-orbitals participating in hybridisation of metal atom may be from the n & (n-1) shell. This depends on the nature of metal and nature of ligand. The complexes involving the inner d-level (inner orbital complexes) results when the ligand is a powerful (or) strong ligand results in a diamagnetic (or) low spin complexes. A weak ligand usually results in the formation of outer orbital complex (or) high spin complex.
The hybridisation of Cu in `[CuCl_(4)]^(2-)&[Cu(NH_(3))_(4)]^(2+)` are respectivly

A

`dsp^(2),dsp^(2)`

B

`sp^(3),dsp^(2)`

C

`sp^(3),sp^(3)`

D

`dsp^(2),sp^(3)`

Text Solution

Verified by Experts

The correct Answer is:
B
Cu undergoes `sp^(3)` hybridization in `[CuCl_(4)]^(2-)`

In `[Cu(CN)_(4)]^(2-)`, rearrangement of unpaired `e^(-)` takes place as shown and Cu undergoes `dsp^(2)` hybridisation.
