Question

Which of the following hybridisation has square planar geometry?
1 )sp³d
2) dsp³
3) dsp²
4) sp³​

Answer 1

$\huge\tt\colorbox{lime}{Answer}$

3) dsp²

dsp² hybridisation has square planar geometry.

Rules to determine hybridisation of a coordination compound:-

1. Central metal ion release the electron equal to its oxidation state.

2. Metal ion arrange empty orbitals equal to its coordination number.

3. These empty orbital arrange in a specfic geometry.

4.Hybridised orbitals of metal ion forms bonds with the lone pair orbitals.
