what is iodoform reaction
-The iodoform test or reaction is a chemical reaction where iodoform (CHI3) is produced by the multiple halogenation of a methyl ketone (a molecule containing the R-CO-CH3 group) in the presence of a base. R may be H, alkyl or aryl.The reaction can be used to produce CHCl3, CHBr3 or CHI3.thanal is the only aldehyde to give the iodoform reaction. Finally, OH- (aqueous) is added, which reacts with, for example, the triiodoacetone. CH3COCI3 + OH- â CHI3 + CH3COO-Iodoform, or triiodomethane (I3CH) is a pale yellow substance. It is therefore a solid at room temperature.
