Webb1 mars 2016 · Conclusion: It can be said that the objective of this experiment was to synthesize the p-bromonitrobenzene out of bromobenzene by nitration. This experiment studied the electrophilic aromatic nitration of a monosubstituted aromatic cring under a standard set of conditions. http://vms.ns.nl/nitration+lab+report WebbThe mechanism of electrophilic aromatic nitration was revisited. Based on the available experimental data and new high-level quantum chemical calculations, a modification of the previous reaction mechanism is proposed involving three separate intermediates on the potential energy diagram of the reaction. feizhch niglas.ac.cn

"Webbför 20 timmar sedan · 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 the same nitrating mixture of … " - Nitration of bromobenzene experiment
