Web6 jan. 2024 · Iodoform is the organoiodine compound with the formula CHI3. A pale yellow, crystalline, volatile substance, it has a penetrating and distinctive odor (in older chemistry texts, the smell is sometimes referred to as the smell of hospitals, where the compound is still commonly used) and, analogous to chloroform, sweetish taste. WebAny compounds containing the CH3C=O group or the CH3CH (OH) group give a positive result with the iodoform test. When I2 and NaOH is added to a compound containing one of these groups, a pale yellow precipitate of iodoform (triiodomethane) is formed.
