Vedclass · Answer

(A) The acidic strength of hydrohalic acids $(HX)$ 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 dissociation enthalpy decreases.Therefore,the ease of releasing $H^+$ ions increases in the order: $HF Since $HF$ has the strongest $H-X$ bond due to its small size,it is the weakest acid among the given options.
