Question

The CORRECT order of hybridisation of the central atom in the following species. NH₃, [PtCl₄]²⁻, PCl₅, and BCl₃ is [Atomic Number Pt = 78].

TestHub · Accepted Answer

Find hybridization of the central atom:

NH₃ → 3 bond pairs + 1 lone pair = 4 electron pairs → sp³

[PtCl₄]²⁻ → square planar complex of Pt²⁺(d⁸) → dsp²

PCl₅ → trigonal bipyramidal geometry → sp³d

BCl₃ → trigonal planar geometry → sp²

Therefore, the order is:

$s p^{3}, ds p^{2}, s p^{3} d, s p^{2}$
