Nitrobenzene is an organic compound. It is the simplest aromatic nitro compound. These chemicals are also called nitrobenzenes. It has the chemical formula C6H5NO2.
Nitrobenzene is made by adding a nitronium cation to a benzene ring. The nitronium is an electrophile attracted to the aromatic ring of the benzene. This reaction is a type of electrophilic aromatic substitution. The nitronium is normally made from nitric acid and another strong acid like sulfuric acid.
Nitrobenzene can be reduced into aniline. The nitro group reacts with hydrogen gas and a catalyst like Raney nickel.
