Predict the correct order among the following in terms of repulsions:
Lone pair – lone pair > lone pair – bond pair > bond pair – bond pair.
Lone pair – lone pair > bond pair – bond pair > lone pair – bond pair.
Bond pair – bond pair > lone pair – bond pair > lone pair – lone pair.
Lone pair – bond pair > bond pair – bond pair > lone pair – lone pair.
To solve this problem, we need to understand the concept of electron pair repulsions in a molecule.According to VSEPR (Valence Shell Electron Pair Repulsion) theory, the repulsions between electron pairs around a central atom determine the geometry of the molecule.There are three types of electron pair interactions to consider:• Lone pair – lone pair (LP-LP)• Lone pair – bond pair (LP-BP)• Bond pair – bond pair (BP-BP)The order of repulsion strength is determined by the amount of space each type of pair occupies.Lone pairs occupy more space than bond pairs because they are not shared between atoms, leading to greater repulsion.The general order of repulsion strength is:1. Lone pair – lone pair (LP-LP) repulsions are the strongest.2. Lone pair – bond pair (LP-BP) repulsions are intermediate.3. Bond pair – bond pair (BP-BP) repulsions are the weakest.Therefore, the correct order of repulsions is:Lone pair – lone pair > lone pair – bond pair > bond pair – bond pair.This corresponds to Option 1.
