Question

Give the increasing order of reactivity among the following compounds towards aromatic electrophilic substitution. Also give explanation for your order.
a Toluene b Aniline c Benzene d Nitrobenzene e Acetophenone
​

Answer 1

Explanation:

The correct order of reactivity towards the electrophilic substitution of the compounds aniline (I) Benzene (II) Nitrobenzene (III) is $$I > II > III$ $. In aniline, the amino group increases the electron density on the benzene ring and increases the reactivity towards electrophilic aromatic substitution reaction. In nitrobenzene, the electron withdrawing nitro group decreases the electron density of benzene ring and deactivates the ring towards electrophilic aromatic substitution reaction.

Answer 2

Answer:

Correct option is

D

I>II>III

Explanation:

The correct order of reactivity towards the electrophilic substitution of the compounds aniline (I) Benzene (II) Nitrobenzene (III) is $$I > II > III$ $. In aniline, the amino group increases the electron density on the benzene ring and increases the reactivity towards electrophilic aromatic substitution reaction. In nitrobenzene, the electron withdrawing nitro group decreases the electron density of benzene ring and deactivates the ring towards electrophilic aromatic substitution reaction.
