    Ash3 donot undergo hybridization (but usually it is said to be sp3 hybridised similar like nh3)

    In hybridisation we need to have bonding orbitals which have similar energy. The central atom here have vacant d-orbital due to which even when small amount of energy is given out the electrons excite to d-orbitals and can participate in dπ -pπ  bonding. In the case of PH3 , H2S , AsH3 etc. the central atom being non-metal have almost have similar electronegativity as that of hydrogen atom.  Hence they don't undergo hybridisation.
