Explain the non-linear shape of `H_(2)S` and non-planar shape of `PCl_(3)` using valence shell electron pair repulsion theory.

Text Solution

Verified by Experts

Shape of `H_(2)S` The eolectronic configuration of sulphur (Z=16) is 2,8,6. Out of the six valencr electrons, two constitute bond pairs with the electrons of hydrogen atoms while the remaining fhor electeons are in the form of two lone paires. The central sulphur atom is surrounded by two lone pairs and two shared pairs of electrons and to minimise the repulsives interactions in the electron pairs, the shape of the molecule is non-linear (bond angle =`92^(@)`)
Shape of `PCl_(3).` The electronic configuration of phosphorus (Z=15) is 2,8,5 In `PCl_(3)` molecule, three valence electrons of phosphorus from three shared pairs with the electrons of three chlorine atoms and the remaining two electrons from one lone pair.

In order to minimise rthe repulsive interactions in the electron pairs, the spape of the moleculeis non-planar with bond angle nearly `100^(@).`
