Vedclass · Answer

(D) The reaction of hydrogen halides $(HX)$ with ethyl alcohol $(C_2H_5OH)$ involves the cleavage of the $C-O$ bond. The reactivity depends on the strength of the $H-X$ bond. As the size of the halogen atom increases from $F$ to $I$,the bond dissociation energy of the $H-X$ bond decreases,making the bond easier to break. Therefore,the reactivity order is $HI > HBr > HCl > HF$.

The correct order of reactivity of hydrogen halides with ethyl alcohol is
