PH3, H2S, AsH3 and XeH4 Explanation- Because for hybridisation you need to have bonding orbitals having similar energy (not having very large difference) and also the bonding atom should have a higher electronegativity. Due to high electronegativity , the central atom has greater tendency to attract the electrons. In the case such as PH3 , H2S , AsH3 etc. the central atom being a non-metal also they have similar electronegativity as that of Hydrogen. The central atom in each case have vacant d-orbital due to which if small amount of energy is given out the electrons excite to d-orbitals and can participate in d pi -p pi bonding. Here the size of central atom is huge compared to that of Hydrogen, so the hydrogen atoms approach from the axial side hence have a bond angle close to 90 degrees (p-orbitals are axial and the orbitals are mutually perpendicular to each other).
