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.
