Concept introduction:
VSEPR theory stands for Valence Shell Electron Pair Repulsion Theory. It helps to predict the molecular shape or geometry of the molecule with the help of the number of bond pairs or lone pairs present in it.
According to the VSEPR theory, the presence of lone pair on the central atom of a molecule causes deviation from standard molecular geometry. Thus, valence electrons provide a Lewis structure, which gives an idea about electron pair geometry and hybridization.

Explanation of Solution
Given information:
In the
Number of valence electron = Number of atom C (valence electron in C) + Number of atom S (valence electron in S) =
Hence the Lewis structure must be:
Geometry = Linear, bond angle = 180°
In the
Number of valence electron = Number of atom C (valence electron in C) + Number of atom O (valence electron in O)+ Number of atom H (valence electron in H) =
Hence the Lewis structure must be:
Geometry = Trigonal planer, bond angle = 120°
In the
Number of valence electron = Number of atom O (valence electron in O) + Number of atom H (valence electron in H) =
Hence the Lewis structure must be:
Geometry = bent, bond angle = 104°
In
In the
Number of valence electron = Number of atom P (valence electron in P) + Number of atom Cl (valence electron in Cl) =
With sp3 hybridization, the geometry must be tetrahedral but the presence of one lone pair on central P atom alters the standard geometry of molecule to pyramid shape due to repulsion between lone pair and bond pair of the molecule.
Thus,
Lewis structure | molecular shape, | bond angle | hybrid orbitals | |
![]() |
Linear | 180° | sp hybrid orbitals | |
![]() |
Trigonal planer | 120° | sp2 hybrid orbitals | |
![]() |
Bent | 104° | sp3 hybrid orbitals | |
![]() |
Tetrahedral | 109° | sp3 hybrid orbitals | |
![]() |
Pyramid | 107° | sp3 hybrid orbitals |
