WebCompared to benzene, the rate of electrophilic substitution on pyridine is much slower, due to the higher electronegativity of the nitrogen atom. Additionally, the nitrogen in pyridine easily gets a positive charge either by protonation (from nitration or sulfonation) or Lewis acids (such as AlCl 3) used to catalyze the reaction. This makes the ... WebAn explanation of the mechanism for the nitration of benzene - an electrophilic substitution reaction between benzene and nitric acid EXPLAINING THE NITRATION OF BENZENE …
