Which of the following is correct decreasing order of the repulsive interaction of electron pairs in a molecule?
- A lone pair-lone pair \(>\) lone pair-bond pair \(>\) bond pair-bond pair
- B bond pair-bond pair \(=\) bond pair-lone pair \(>\) lone pair-lone pair
- C lone pair-bond pair \(>\) lone pair-lone pair \(>\) bond pair-bond pair
- D bond pair-bond pair \(>\) lone pair-bond pair \(>\) lone pair-lone pair
Answer & Solution
Correct Answer
(A) lone pair-lone pair \(>\) lone pair-bond pair \(>\) bond pair-bond pair
Step-by-step Solution
Detailed explanation
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.
