at first, this step takes place because there is a requirement for stronger electrophile and for that nitric acid has to be activated for nitration of benzene.• Sulphuric activates nitric acid and produces a strong electrophile nitronium ion NO2+, its electrophilicity tends to attack the benzene ring and electrophillic substitution takes place by producing nitrobenzene.•The other 3 species (i) NO2(ii) NO+ and (iv) NO2– cannot be formed during the activation of nitric acid.

Answer :

at first, this step takes place because there is a requirement for stronger electrophile and for that nitric acid has to be activated for nitration of benzene.

• Sulphuric activates nitric acid and produces a strong electrophile nitronium ion NO₂⁺, its electrophilicity tends to attack the benzene ring and electrophillic substitution takes place by producing nitrobenzene.

•

The other 3 species (i) NO₂(ii) NO⁺ and (iv) NO₂^– cannot be formed during the activation of nitric acid.
