Thermal stability

Vedclass · Answer

(B) The thermal stability of hydrides of the oxygen family $(H_2O, H_2S, H_2Se, H_2Te)$ decreases regularly on moving down the group due to the increase in bond length and decrease in bond dissociation enthalpy.Specifically,the order of thermal stability is: $H_2O > H_2S > H_2Se > H_2Te$.Other properties like melting point,boiling point,and critical temperature do not change regularly due to the anomalous behavior of $H_2O$ caused by hydrogen bonding.

In the case of hydrides of the oxygen family,which of the following physical properties changes regularly on moving down the group?
