Definition of Haloform Reaction



Haloform​ Reaction is a chemical reaction in which there is a production of haloform (CHX3​). ​ The reaction takes place in the presence of hydroxide ions. The end products of the reaction are haloform and a carboxylate ion. Haloform is produced when a methyl ketone is halogenated (addition of a halogen) in the presence of a base.

 


The main application of this reaction is to produce chloroform (CHCl3​) ​, bromoform (CHBr​3), and iodoform (CHI3​)​ at an industrial scale. This is also performed to transform the acetyl groups into carboxyl groups. There is only one aldehyde that undergoes such a type of reaction and that is acetaldehyde.
