Question

What is the order of thermal stability of the hydrides of group 16 element . ​

Answer 1

Answer:

H2O > H2S> H2Se > H2Te> H2po

Explanation:

The thermal stability of hydrides of group 16 elements is directly proportional to bond dissociation enthalpy of H-E Bond on moving down the group , bond dissociation energy decrease because bond length increase .

Thus , the order of bond dissociation energy is

H20> H2S>H2Se > H2Te> H2Po
