Vedclass · Answer

(B) The reaction of alcohols with hydrogen halides $(HX)$ in the presence of $ZnX_2$ (Lucas reagent) follows the mechanism where the bond strength of $H-X$ determines the reactivity. As the size of the halogen atom increases,the bond dissociation energy of the $H-X$ bond decreases,making it easier to break. The bond dissociation energy order is $HI Therefore,the reactivity order for the reaction is $HI > HBr > HCl$.

What is the order of reactivity for the reaction ${{C}_{2}}{{H}_{5}}OH + HX \xrightarrow{Zn{{X}_{2}}} {{C}_{2}}{{H}_{5}}X + {{H}_{2}}O$?
