Interpretation:
The VSEPR bonding theory needs to be summarized.
Concept introduction:
The covalent bonding in molecules can be explained on the basis of Lewis structure and Hybridization.
The Lewis structure of an organic compound represents the bonding of atoms with lone pairs (if any). It indicates the bonds with atoms and the arrangement of atoms in a molecule.

Answer to Problem 61SSC
The VSEPR theory can be summarized as:
- The presence of a lone pair on the central atom affects the molecular geometry of a molecule.
- The order of repulsion is lone pair-lone pair > lone pair-bond pair > bond pair-bond pair.
- The electro negativity of bonded atoms affects the position of bond pairs and it further affects the bond angle.
Explanation of Solution
VSEPR theory stands as 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. The VSEPR theory can be summarized as:
- The presence of a lone pair on the central atom affects the molecular geometry of the molecule.
- The order of repulsion is lone pair-lone pair > lone pair-bond pair > bond pair-bond pair.
- The electro negativity of bonded atoms affects the position of bond pairs and it further affects the bond angle.
