Vedclass · Answer

(A) The thermal stability of hydrides decreases on moving down the group.This is due to a decrease in the bond dissociation enthalpy ($E-H$ bond) of hydrides as the size of the central atom increases down the group.Therefore,the correct order of thermal stability is:$H_2O > H_2S > H_2Se > H_2Te > H_2Po$

Write the order of thermal stability of the hydrides of Group $16$ elements.
