WebbBenzene is nitrated with a mixture of conc nitric acid and conc sulphuric acid to form nitrobenzene. Temperature is kept below 100 deg C to prevent further nitration to meta … WebbThe nitration process involves formation of the nitronium ion (NO 2+ ), followed by an electrophilic aromatic substitution reaction of it with benzene. The nitronium ion is generated by the reaction of nitric acid …
WebbA kind of nitrogen oxides (NO x ) nitrify the method that benzene prepares nitrobenzene, i.e. one kind being transferred to " non-acid " method from " strong acid " method, … The reduction of nitro compounds are chemical reactions of wide interest in organic chemistry. The conversion can be effected by many reagents. The nitro group was one of the first functional groups to be reduced. Alkyl and aryl nitro compounds behave differently. Most useful is the reduction of aryl nitro compounds.
