The iodoform test or iodoform reaction is a qualitative chemical test for the detection of ketones and aldehydes carrying an alpha methyl group. The reagents are iodine and sodium hydroxide.Only methyl ketones, or alcohols with the feature: CH3CH(OH)-R may undergo this reaction.The iodoform test or reaction is a chemical reaction where iodoform (CHI3) is produced by the multiple halogenation of a methyl ketone (a molecule containing the R-CO-CH3 group) in the presence of a base. R may be H, alkyl or aryl.
Iodoform is the organoiodine compound with the formula C H I 3. A pale yellow, crystalline, volatile substance, it has a penetrating odor (in older chemistry texts, the smell is sometimes referred to as the smell of hospitals) and, analogous to chloroform, sweetish taste. It is occasionally used as a disinfectant.t is synthesized in the haloform reaction by the reaction of iodine and sodium hydroxide with any one of these four kinds of organic compounds: (i) a methyl ketone: CH 3 COR, acetaldehyde (CH 3 CHO), ethanol (CH 3 CH 2 OH), and certain secondary alcohols (CH 3 CHROH, where R is an alkyl or aryl group).
