WebJan 23, 2024 · Nitration and sulfonation of benzene are two examples of electrophilic aromatic substitution. The nitronium ion (NO 2+) and sulfur trioxide (SO 3) are the electrophiles and individually react with benzene to give nitrobenzene and benzenesulfonic acid respectively. Nitration of Benzene WebJul 29, 2014 · The first reaction is called a catalytic reduction. Here is a picture of how it works with an olefin like ethylene.

WebThe mechanism for the nitrobenzene reaction occurs in six steps. 1. Sulfuric acid ionizes to produce a proton. 2. Nitric acid accepts the proton in an acid‐base reaction. 3. The protonated nitric acid dissociates to form a nitronium ion ( + NO 2 ). 4.
WebReacting methylbenzene with a mixture of concentrated nitric and sulphuric acids gives both 2-nitromethylbenzene and 4-nitromethylbenzene. The mechanism is exactly the same as the nitration of benzene. You just have to be careful about the way that you draw the structure of the intermediate ion.
