The iodobenzaldehydes form a group of substances in chemistry that are derived from both benzaldehyde and iodobenzene . The structure consists of a benzene ring with attached aldehyde group (-CHO) and iodine (-I) as substituents . Their different arrangements ( ortho , meta or para ) result in three constitutional isomers with the empirical formula C 7 H 5 IO.
