What is the order of reactivity of following halogen acids on alcohols...
That atomic size increases from F to I, so bond length of H-X bond also gets increased and so bond dissociation energy decreases. Hence, ionisation of H-X increases, therefore acidic strength increases in the order
HF < HCl < HBr < HI

So, the reactivity of alcohols towards haloacids is in the order - HI>HBr>HCl

What is the order of reactivity of following halogen acids on alcohols...
Due to less electronegativity I has the ability to release H+ ion more easily, then comes HBr and HCl.
