Reaction that produce nitrobenzene
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 ... WebApr 8, 2024 · Introduction. Photoreactions of nitrobenzene derivatives have been studied since the early 1900s, [Citation 1] and three types of possible reactions are currently known: intermolecular H abstraction, intramolecular H abstraction, and addition to double bond. [Citation 2, Citation 3] In a typical intermolecular H abstraction, a nitro radical produced by …

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.
