Benzene is treated with a mixture of concentrated nitric acid and concentrated sulfuric acid at a temperature not exceeding 50°C. As temperature increases there is a greater chance of getting more than one nitro group, -NO 2, substituted onto the ring. Nitrobenzene is formed:HNO2 is also known as ‎Dioxonitric (III) acid. It is a weak acid and exists only in specific conditions, i.e., in solution (cold and dilute), as a gas, or in the form of nitrite salts. It appears to be pale blue as a solution. Its existence in these peculiar states is due to the fact that HNO2 is unstable and decomposes rapidly in its free form.
