MHT CET 2026 Chemistry question

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

(A)Bp-Bp > Lp-Bp > Lp-Lp
(B)Lp-Lp > Lp-Bp > Bp-BpCorrect
(C)Lp-Bp > Bp-Bp > Lp-Lp
(D)Lp-Lp > Bp-Bp >Lp-Bp

Answer: (B)

Solution

According to VSEPR theory a lone pair (Lp) is attracted only by the central nucleus and therefore occupies more space (is more diffuse) than a bond pair (Bp), which is held between two nuclei. Hence the repulsion order is $Lp-Lp > Lp-Bp >
