Write the order of thermal stability of hydrides of group 16 elements.

Asked by Topperlearning User | 10th Jun, 2014, 09:24: AM

Expert Answer:

On moving down the group, there is a decrease in the bond dissociation enthalpy(H-E) of hydrides with increase in atomic size.

So the thermal stability of hydrides decreases down the group.

H2O > H2S > H2Se>H2Te> H2Po
