In the haloform reaction, the trihalogenated intermediate (−CO−CX₃) formed is then subjected to a
nucleophilic attack by the hydroxide ion (OH⁻) at the carbonyl carbon (C=O) producing a tetrahedral
intermediate, which eventually breaks down, expelling the −CX₃ group and leading to the formation of a
carboxylate anion.
