JEE Advanced 2024 Chemistry question

ChemistryChemical Bonding and Molecular StructureJEE Advanced 2024

Based on **VSEPR** model, match the xenon compounds given in **List-I** with the corresponding geometries and the number of lone pairs on xenon given in **List-II** and choose the correct option. List-I (P) (Q) (R) (S) List-II (1) Trigonal bipyramidal and two lone pair of electrons (2) Tetrahedral and one lone pair of electrons (3) Octahedral and two lone pair of electrons (4) Trigonal bipyramidal and no lone pair of electrons (5) Trigonal bipyramidal and three lone pair of electrons

Answer: (B)

Solution

Electron-pair geometry from the steric number: : 2 bp + 3 lp = 5 → trigonal bipyramidal, 3 lone pairs (5). : 4 bp + 2 lp = 6 → octahedral, 2
