Give reason for the following :
Thermal stability decreases from `H_(2)O` to `H_(2)` Te.

Text Solution

Verified by Experts

Thermal stability of hydrides decrease on moving down the group. This is due to the decrease in the bond dissociation enthalpy (H-E) of hydrides on moving down the group where E = O, S , Se, Te.
