The iodonitrobenzenes form a group of substances in chemistry that are derived from both nitrobenzene and iodobenzene . The structure consists of a benzene ring with attached nitro group (–NO 2 ) and iodine (–I) as substituents . Their different arrangement results in three constitutional isomers with the empirical formula C 6 H 4 INO 2 .
properties
The p -iodonitrobenzene, which has the highest symmetry, has the highest melting point.
