Vedclass · Answer

(A) The reactivity of cycloalkanes towards addition reactions is governed by ring strain.According to Baeyer's strain theory,the ring strain decreases as the ring size increases from $3$ to $5$ members.$(I)$ Cyclopropane has the highest ring strain ($60^{\circ}$ bond angle),making it the most unstable and most reactive towards addition reactions.$(II)$ Cyclobutane has intermediate ring strain ($90^{\circ}$ bond angle).$(III)$ Cyclopentane has the lowest ring strain ($108^{\circ}$ bond angle),making it the most stable and least reactive towards addition reactions.Therefore,the order of reactivity is $I > II > III$.

The correct order of reactivity of $(I)$,$(II)$,and $(III)$ towards addition reactions is:
$(I)$ Cyclopropane
$(II)$ Cyclobutane
$(III)$ Cyclopentane
