Question

The correct order of hybridisation of the central atom in following species NH₃, [PtCl₄]²⁻, PCl₅, BCl₃ is: (At. No. Pt = 78)

पर्याय

• dsp², dsp³, sp² and sp³

• sp³, dsp², dsp³, sp²

• dsp², sp², dsp³, sp³

• dsp², sp³, sp², dsp³

Answer 1

sp³, dsp², dsp³, sp²

Explanation:

• NH₃ → 3 bonds + 1 lone pair = 4 bonds → sp³
• [PtCl₄]²⁻ → Pt²⁺ (d⁸), square planar → dsp²
• PCl₅ → 5 bonds, trigonal bipyramidal → dsp³
• BCl₃ → 3 bonds, trigonal planar → sp²
