In the presence of excess base and excess halogen, a methyl ketone is converted into a carboxylate ion. The reaction is known as the haloform reaction because one of the products is haloformeither chloroform, bromoform, or iodoform. Before spectroscopy became a routine analytical tool, the haloform reaction served as a test for methyl ketones: the formation of iodoform, a bright yellow compound, signaled that a methyl ketone was present. Why do only methyl ketones form a haloform?
