In aromatic nitration reactions, nitric acid (HNO₃) is used in conjunction with the stronger acid, sulfuric acid, H₂SO₄, to form an intermediate. Which of the following could be the formula for this intermediate?

Question

Quizplus · Accepted Answer

The intermediate formed in aromatic nitration reactions involves the formation of a nitronium ion (NO2+) from nitric acid and sulfuric acid. This nitronium ion then reacts with the aromatic compound to form the nitroaromatic product. The formula for this intermediate can be written as H₂NO₃⁺. None of the other options accurately represent the formation of the nitronium ion intermediate. Option A only represents the nitrate ion from nitric acid, Option B includes an additional sulfuric acid molecule not present in the intermediate, and Option D only represents nitric acid.
