The relative reactivity order of the following halides towards Sn1 reaction is: (I) (II) CH3–CH2–Cl (III) CH3Cl (IV) Ph2CHCl
(IV) > (I) > (II) > (III)
The reactivity of halides towards Sn1 reaction generally increases with the number of alkyl groups attached to the carbon bonded to the halogen. In this case, (IV) Ph2CHCl is the least reactive, while (I) CH3–C–Cl (CH3) is the most reactive. Therefore, the correct order is (IV) > (I) > (II) > (III).
