Incorrectly matched characteristic is : — p Block Elements Chemistry Question

💡 Solution & Explanation

Step 1: Analyze each substance and its solid-state structure: SiO2 forms a giant 3D covalent network (covalent lattice); P4 forms discrete tetrahedral molecules; sulfur exists as discrete S8 ring molecules. Step 2: In solid sulfur, these S8 molecules are held together by weak intermolecular van der Waals forces, making it a molecular solid rather than a giant covalent lattice. Step 3: Therefore, 'S8: Covalent lattice' is an incorrect match, which corresponds to option (a).
