Vedclass · Answer

(B) The thermal stability of hydrogen halides $(HX)$ depends on the bond dissociation enthalpy of the $H-X$ bond.As the size of the halogen atom increases from $F$ to $I$,the bond length increases and the bond strength decreases.Therefore,the order of bond dissociation energy is $HF > HCl > HBr > HI$.Consequently,the correct order of thermal stability is $HF > HCl > HBr > HI$.

The correct order of the thermal stability of hydrogen halides $(HX)$ is:
