Question

What happen , when Benzene is treated with concentrated H2SO4 at 330 K ?

Answer 1

Explanation:

Benzene will be converted in benzene sulphonic acid via electrophilic addition reaction. In this reaction active species is SO3 and also the electrophile. What happens when benzene is heated with concrete, H2SO4 at 250 degree C

Answer 2

Nitration of Benzene

Explanation:

• Benzene when treated with concentrated nitric acid and sulfuric acid at 330K temperature it forms nitrobenzene that is nitration occurs
• The reaction is highly explosive and risky as a lot of heat is evolved during the reaction
• The nitration of benzene starts with the activation of $HNO_3$ with sulfuric acid that is through the protonation of nitric acid by sulfuric acid.
• After the protonation, it produces a strong electrophile, the nitronium ion and loses a water molecule as a by-product
• After the formation of nitronium ion it attacks the benzene ring for the formation of the product Nitrobenzene
