Iodoform test acetone

WebThe reaction mechanism for the haloform test occurs under basic conditions. First, the ketone undergoes a keto-enol tautomerization. Then the nucleophilic enolate attacks the iodine to give an iodine ion and a halogenated ketone. This repeats a total of three times until all hydrogens of the ketone methyl group are replaced by an iodine. WebIodoform test is given by those compounds which has COCH3 group and also those alcohols which produces the CH3CO group on oxidation so here in this case acetone has COCH3 group and ethanol on oxidation produces CH3CHO so it also has CH3CO group but in diethyl ketone we have CH3CH2COCH2CH3 means we have ethyl group so that is …
