The principal types of reactions involving aromatic rings are substitution, addition, … In chemistry, the haloform reaction is a chemical reaction in which a haloform (CHX3, where X is a halogen) is produced by the exhaustive halogenation of an acetyl group (R−C(=O)CH3, where R can be either a hydrogen atom, an alkyl or an aryl group), in the presence of a base. The reaction can be used to transform acetyl groups into carboxyl groups (R−C(=O)OH) or to produce chloroform (CHCl…

The aldehyde is attacked at the electrophilic carbonyl carbon by the nucleophilic enolate ion. This attack is a nucleophilic addition reaction and gives alkoxide intermediate. The alkoxide deprotonates water molecule, thereby producing hydroxide and the β–hydroxy aldehyde.
