Question
CBSEENCH12006649

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

Solution

The thermal stability of hydrides decreases on moving down the group. This is due to a decrease in the bond dissociation enthalpy of hydrides on moving down the group.
Therefore,

H2O>H2S>H2Se>H2Te>H2PO
