Which of the following is correct regarding repulsive interaction?

(a) Lone pair-Lone pair is greater than Lone pair-Bond pair is greater than Bond pair-Bond pair

(b) Lone pair-Lone pair is less than Lone pair-Bond pair is less than Bond pair-Bond pair

(c) Lone pair-Bond pair is greater than Lone pair-Lone pair is greater than Bond pair-Bond pair

(d) Lone pair-Lone pair is greater than Lone pair-Bond pair is less than Bond pair-Bond pair

This question was posed to me in homework.

Query is from Valence Shell Electron Pair Repulsion (VSEPR) Theory in portion Chemical Bonding and Molecular Structure of Chemistry – Class 11

Right option is (a) Lone pair-Lone pair is greater than Lone pair-Bond pair is greater than Bond pair-Bond pair

Explanation: The repulsive interactions follow the above order. The lone pairs are localized on the central atom, each bonded pair is shared between two atoms. So, the lone pair electrons in a molecule occupy more space as compared to the bonding pairs of electrons.
