Aryl halides are less reactive towards nucleophilic substitution reaction as compared to alkyl halide due to 

Arrange the following compounds in incrensing order of their rate of reaction towards hydroxyl ion $\left({\mathrm{OH}}^{-}\right)$.

I 

II

III 

IV 

Identify the relation among the rates of following nucleophilic substitution reactions?

The correct order of the following compounds showing increasing tendency towards nucleophilic substitution reaction is:

The rates of reaction of $\mathrm{NaOH}$ with:

follow the order:-

Write the product formed when p-nitrochlorobenzene is heated with aqueous $\mathrm{NaOH}$ at 443 K followed by acidification.

Give reasons:

The presence of the nitro group $\left(-{\mathrm{NO}}_2\right)$ at 0/p positions increases the reactivity of haloarenes towards nucleophilic substitution reactions.
