Identify correct order for repulsion between electron pair present in valence shell of central atom of molecule?

Step-by-step solution

According to VSEPR theory, the electron pairs in the valence shell of the central atom repel each other to minimize electron-electron repulsion. Lone pairs (Lp) are localized on the central atom and are attracted by only one nucleus, so they occupy more space and exert greater repulsion. Bond pairs (Bp) are shared between two atoms and are attracted by two nuclei, so they occupy less space and exert lesser repulsion. Thus, the correct order of repulsion between electron pairs is Lp-Lp > Lp-Bp > Bp-Bp . Answer: Lp-L
