WebbThe 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 ...
WebbThe 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. county winchester nhWebbNitration [HNO 3 /H2SO 4] Definition: Aromatic groups can be nitrated by the action of nitric acid and an acid catalyst in the reaction of electrophilic aromatic substitution. … brian and charles birminghamWebb16 juli 1993 · Process for the preparation of 2,3-dichloro-nitrobenzene.
