Question
Arrange the following in the increasing order of the property mentioned:
\[\ce{HF}\], \[\ce{HCl}\], \[\ce{HBr}\], \[\ce{HI}\] (thermal stability)

Solution
Thermal stability of hydrogen halides increases in the following order:
\[\ce{HI < HBr < HCl < HF}\]
It is due to the decrease in bond dissociation enthalpy of \[\ce{H - X}\] bond down the group.
