Predict the correct order among the following:

  1. A
    Lone pair – lone pair > bond pair – bond pair > lone pair – bond pair
  2. B
    Bond pair – bond pair > lone pair – bond pair > lone pair – lone pair
  3. C
    Lone pair – bond pair > bond pair – bond pair > lone pair – lone pair
  4. D
    Lone pair – lone pair > lone pair – bond pair > bond pair – bond pair

Solution & Step-by-step Explanation

According to VSEPR theory, the magnitude of repulsion between electron pairs follows the order:

This is because lone pairs are localized only on the central atom and occupy more space compared to bond pairs.
