    Predict the order of reactivity of following compounds in \[{{S}_{{{N}^{1}}}}\] reactions.                                      

    Answer:

                    Except for chlorocyclohexane which is a secondary halide, the other compounds are tertiary halides in nature. We know that tertiary halides are more reactive than secondary halides in \[{{S}_{{{N}^{1}}}}\] reactions. Moreover, the order of the cleavage of \[C-X\] bonds is: \[C-I>C-Br>C-Cl\]. Based on these guidelines the increasing order of reactivity of the cyclic compounds listed above is:
