Which of the following is correct decreasing order of the repulsive interaction of electron pairs in a molecule?

Options

  1. Alone pair-lone pair > lone pair-bond pair > bond pair-bond pair
  2. Bbond pair-bond pair = bond pair-lone pair > lone pair-lone pair
  3. Clone pair-bond pair > lone pair-lone pair > bond pair-bond pair
  4. Dbond pair-bond pair > lone pair-bond pair > lone pair-lone pair

Correct answer

A. lone pair-lone pair > lone pair-bond pair > bond pair-bond pair

Step-by-step solution

In a molecule, the correct decreasing order of the repulsive interectlon of electron pairs is, lone pair-lone pair > lone pair-bond pair > bond pair-bond pair. Two atoms share bond pairs of electrons, whereas the lone pair of electrons is only influenced by the central atom. As a result, the electron cloud of a lone pair takes up more space than that of a bond pair. The lone pair-lone pair repulsion is increased as a result of this.
