AlkyI halides are more reactive than aryl halides. Among alkyl halides, 3° alkyl halides (III) are more reactive than 2° alkyl halides. (IV) Among aryl halides, aryl halides having electron with dwawing -NO2 groups at o- and p- positions (i.e. II) are more reactive than simple aryl halides (I) thus, the overall reactivity increases in the order. I<II<IV<III
