Question

In the nitration of benzene using a mixture of conc. H₂SO₄
and conc. HNO₃, the species which initiates the reaction
is ............ .
(a) NO₂ (b) NO⁺
(c) NO₂⁺ (d) NO₂⁻

Answer 1

The species which initiates the reaction  is NO₂⁺.

Option (C) is correct.

Explanation:

• At first of the reaction, this step takes place because there is a requirement for stronger electrophile.
• For this purpose the nitric acid is considered an activated compound for the nitration of benzene.
• Sulphuric activates nitric acid.
• It produces a strong electrophile nitronium ion NO2+.
• Its has high electrophilicity tends that attacks the benzene ring.
• Electrophillic substitution also takes place by producing nitrobenzene.

Thus the species which initiates the reaction  is NO₂⁺.
