What is the order of decreasing repulsion for electron pair interactions?

Options

  1. ALone pair (lp) – Bond pair (bp) > Lone pair (lp) – Lone pair (lp) > Bond pair (bp) – Bond pair (bp)
  2. BLone pair (lp) – Lone pair (lp) > Bond pair (bp) – Bond pair (bp) > Lone pair (lp) – Bond pair (bp)
  3. CBond pair (bp) – Bond pair (bp) > Lone pair (lp) – Lone pair (lp) > Lone pair (lp) – Bond pair (bp)
  4. DBond pair (bp) – Bond pair (bp) > Lone pair (lp) – Bond pair (bp) > Lone pair (lp) – Lone pair (lp)

Correct answer

C. Bond pair (bp) – Bond pair (bp) > Lone pair (lp) – Lone pair (lp) > Lone pair (lp) – Bond pair (bp)

Step-by-step solution

The repulsive interaction of electron pairs decreases in the order: Lone pair (lp) – Lone pair (lp) > Lone pair (lp) – Bond pair (bp) > Bond pair (bp) – Bond pair (bp).
