Problem
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 ≤2.5 .
In which of the following option, covalent bond is having maximum s% character?
(1) S — H bond in H2S
(2) P — H bond in PH3
(3) N — H bond in NH3
(4) All have equal s% character
