Reaction that produce nitrobenzene
WebThe lone pair on the nitrogen in the phenylamine picks up a hydrogen ion from the acid. The electron-half-equation for this reaction is: The nitrobenzene has been reduced by gaining electrons in the presence of the acid. The electrons come from the tin, which forms both tin (II) and tin (IV) ions. WebJan 23, 2024 · Nitrobenzene is formed: C6H6 + HNO3 → C6H5NO2 + H2O or: The concentrated sulfuric acid is acting as a catalyst. The formation of the electrophile The …

WebThus nitrobenzene (a deactivated ring) fails to react in the Friedel-Crafts reaction. However the reaction is successful with halogen substituents are present, as in chlorobenzene. The Friedel-Crafts alkylation of methoxy benzene would be expected to produce a mixture of the ortho and para substituted products, but no meta -substituted product. WebThe mechanism for nitration of benzene: Step 1: Nitric acid accepts a proton from sulphuric acid and then dissociates to form nitronium ion. Step 2: The nitronium ion acts as an electrophile in the process which further reacts with benzene to form an arenium ion. Step 3: The arenium ion then loses its proton to Lewis base forming nitrobenzene.
WebYes, NO₂ is more deactivating than Br, but you can compensate for this by raising the temperature. There are many factors that affect yield. For example, bromination of nitrobenzene gives an 80% yield of m-bromonitrobenzene. Nitration of bromobenzene gives a 50% yield of p-bromonitrobenzene.
