18.4: Sulfonation of Benzene (an EAS Reaction)

WebIn the nitration of benzene, reagent used is HN O 3 & H 2 S O 4 . With the help of this mixture of acids, N O 2 + − electrophile is generated. Reaction is occurred via the electrophilic substitution reaction and nitrobenzene is formed. WebThe nitration of methylbenzene (toluene) Methylbenzene reacts rather faster than benzene - in nitration, the reaction is about 25 times faster. That means that you would use a lower temperature to prevent more than one nitro group being substituted - in this case, 30°C rather than 50°C. Apart from that, the reaction is just the same - using ... WebSep 26, 2024 · Get what activating and deactivating groups in fundamental chemistry?

Explaining the nitration of benzene - electrophilic substitution

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.
