The correct order of hybridisation of the central atom in the
following species :
NH₃, [PtCl₄]²⁻, PCl₅ and BCl₃ is
(a) dsp², dsp³, sp², sp³ (b) sp³, dsp², dsp³, sp²
(c) dsp², sp², sp³, dsp³ (d) dsp², sp³, sp², sp³

Option [A] is the answer ✔️

Answer 2

sp³, dsp², dsp³, sp² is the correct order of hybridisation of the molecules.

Explanation:

• The hybridization is the concept of blending of the orbitals of a central atom into a similar energy state which is formed of different orbitals.

• Here among the molecules, the ammonia contains a lone pair and three bond pairs of electrons.

• So the hybridization is sp3.

• The [PtCl₄]²⁻ contains no lone pairs, but for coordinate covalent bonds of chlorine around it.

• So the hybridization is dsp2.

• The PCl₅ or phosphorous pentachloride contains 5 bonds with chlorine.

• So it forms sp3d hybridization.

• BCl₃ is a planar compound with only 3 bonds around it.

• So it forms sp2 hybridization.
