WebA methyl ketone reacts with a halogen under strongly basic conditions to give a carboxylate ion and a molecule of haloform. The trihalomethyl intermediate is not isolated. Final Steps of the Haloform Reaction. The trihalomethyl ketone reacts with hydroxide ion to give a carboxylic acid. A fast proton exchange gives a carboxylate ion and a haloform.
