Give mechanism of nitration of benzene
WebThe chlorine cation acts as our electrophile. It reacts with benzene, forming chlorobenzene (C6H5Cl) and a hydrogen ion. Like in the nitration reaction, the hydrogen ion reacts with the aluminium tetrachloride ion produced earlier to reform our catalyst, aluminium chloride. This also produces hydrochloric acid (HCl). WebThe nitration formulation of benzene and other arenes (ArH) by NO 2 + can be described such a successive mechanism [9]. Under the action of NO 2 + , the reactants forms π complex and then directly transforms into σ complex, followed by proton transfers to produce the substitution product.

WebNitration of Benzene. Benzene reacts with concentrated nitric acid at 323-333K in the presence of concentrated sulphuric acid to form nitrobenzene. This reaction is known as nitration of benzene. The mechanism for nitration of benzene: Step 1: Nitric acid accepts a proton from sulphuric acid and then dissociates to form nitronium ion. WebApr 8, 2024 · Benzene is a colorless liquid that was first discovered by Michael Faraday in 1825. The molecular formula of benzene is C6H6. Halogenation of Benzene, Nitration of Benzene, Sulfonation of Benzene and Alkylation and Acylation of Benzene are some various chemical reactions of Benzene.

WebApplications Of Nitration. With the help of nitration reaction nitrogen is added to a benzene ring which can be used extensively in substitution reactions. The nitro group usually acts as a ring deactivator. As the ring consists of nitrogen it is very useful because it can be used as a directing group or a masked amino group.
