WebThe haloform reaction is characteristic for methylketones as well as for alcohols (e.g. ethanol, 2-propanol), that can be oxidized to methyl carbonyl compounds. ... Heat the reaction mixture in a water bath (~75°C) for 20 minutes. During the heating, frequently shake the test tube to ensure mixing of the reagents. WebJan 23, 2024 · Overall the haloform reaction represents an effective method for the conversion of methyl ketones to carboxylic acids. Typically, this reaction is performed using iodine because the subsequent iodoform (CHI 3) is a bright yellow precipitate which is easily filtered off.

WebHaloform Reaction: When a methyl ketone (even acetaldehyde) is reacted with halogen in aqueous sodium hydroxide, the ketone gets oxidised to the sodium salt of acid with one carbon less than ketone and at the same time haloform (CHX 3) also gets formed. When the reaction is carried with iodine, a yellow precipitate of iodoform is obtained.
