The Correct Order of Reactivity Towards Electrophilic Substitution is:

The correct order of reactivity towards the electrophilic substitution of the compounds (I)Aniline, (II)Benzene and (III)Nitrobenzene is:

A.  I > II > III

B.  III > II > I

C.  II > III > I

D.  III > I > II

Detailed Explanation

The correct option is  A.  I > II > III.

Arrow

A nitro group is an electron-withdrawing group. It removes electron density from the aromatic nucleus.

Nitro Group

Thus, nitrobenzene(C₆H₅NO₂) is less reactive toward electrophilic aromatic substitution reactions.

Nitrobenzene

An amino group is an electron-releasing group. They increase the electron density on the benzene ring.

Benzene Ring

As a result, aniline(C₆H₅NH₂) is more reactive than benzene toward electrophilic aromatic substitution reactions.
