The specific chemical structures (I, II, III, and IV) are missing from the question data, making it impossible to evaluate the exact order. However, according to general principles, the reactivity of the C-X bond towards nucleophilic substitution in haloarenes is exceptionally low due to resonance and $sp^2$ hybridisation of the carbon atom. This reactivity increases significantly when electron-withdrawing groups (such as $-NO_2$) are introduced at the ortho- and para- positions, as they stabilise the intermediate carbanion . Conversely, typical alkyl, allyl, and benzyl halides are generally much more reactive towards nucleophiles than unsubstituted aryl or vinyl halides.
