Vedclass · Answer

(A) The reaction of hydrogen halides $(HX)$ with alkenes is an electrophilic addition reaction. The rate of reaction depends on the ease of breaking the $H-X$ bond. The bond dissociation energy decreases as the size of the halogen atom increases $(HF > HCl > HBr > HI)$. Therefore,the reactivity order is $HF < HCl < HBr < HI$.

Arrange $HI$,$HCl$,$HBr$,and $HF$ in increasing order of rate of reaction with alkene.
