Reactive species in nitration of benzene
WebBenzene is a ubiquitous industrial and environmental pollutant; hydroquinone as a reactive metabolite of benzene is known to cause myelotoxicity and leukemogenicity in humans. The purpose of our investigation was to understand the mechanism by which hydroquinone induces apoptosis in human chronic myelogenous leukemia K562 cells. WebNitration of Benzene Benzene reacts with concentrated nitric acid at 323-333K in the presence of concentrated sulphuric acid to form nitrobenzene. This reaction is known as nitration of benzene.

Reactive nitrogen species are also involved in the transformation of micropollutants by the UV/monochloramine process. WebAttacking or reactive or electrophilic species in nitration of benzene is or in the nitration of benzene with concentrated HN O3 and H2SO4 the attack on the ring is made by A N O− 2 B N O+ 2 C N O− 3 D N O+ Solution The correct option is B N O+ 2 Electrophilic species in nitration of benzene is N O+ 2.

WebIn table 1, you can see that some substituents confer a rate of reaction that is much higher than that of benzene (R = H). Phenol, C 6 H 5 OH, undergoes nitration a thousand times faster than benzene does. Nitrobenzene, C 6 H 5 NO 2, undergoes the reaction millions of times more slowly.
