Which is not correctly matched? — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: Analyze the geometry of XeO3: Xenon forms 3 double bonds with Oxygen, leaving 1 lone pair. Steric number = 3 sigma domains + 1 lone pair = 4. Step 2: A steric number of 4 with 1 lone pair corresponds to sp3 hybridization and a trigonal pyramidal shape. Step 3: Since XeO3 is trigonal pyramidal and not trigonal bipyramidal, option (a) is the incorrect match.
