Vedclass · Answer

(A) The reactivity of hydrogen halides $(HX)$ towards alcohols 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.Therefore,the ease of cleavage of the $H-X$ bond increases in the order $HF Thus,the decreasing order of reactivity is $HI > HBr > HCl > HF$.

What is the decreasing order of reactivity of $HX$ in the reaction $ROH + HX \to RX + H_2O$?
