If the central atom is of third row or below this in the periodic table, then lone pair will occupy a stereochemically inactive s-orbital and bonding will be through almost pure p-orbitals and bond angles are nearly `90^(@)`, if the substituent's electronegativity value is `le 2.5`.   The hybridisation of atomic orbitals of central atom "Xe" in `XeO_(4), XeO_(2)F_(2) and XeOF_(4)` respectively.
