In which of the following species maximum atom can lie in same plane? — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: Determine the molecular geometries: XeF2O2 is see-saw (5 domains), PCl5 is trigonal bipyramidal (5 domains), AsH4+ is tetrahedral (4 domains), and XeF4 is square planar (6 domains, 4 bond pairs + 2 lone pairs). Step 2: In square planar XeF4, all 5 atoms (the central Xenon and the 4 fluorine atoms) lie in the exact same plane. Step 3: Since all 5 atoms of XeF4 lie in a single plane, it has the maximum number of coplanar atoms among the options, corresponding to option (d).
