The iodoform test or iodoform reaction is a qualitative chemical test for the detection of ketones and aldehydes carrying an alpha methyl group. The reagents are iodine and sodium hydroxide.Only methyl ketones, or alcohols with the feature: CH3CH(OH)-R may undergo this 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.
Iodine is often used to test foods for starch. Adding iodine to potatoes, dried beans, rice, bread and pasta creates the deep blue reaction to indicate the presence of starch. To perform the test, use a dropper to add one or two drops of iodine to each type of food. Use other foods that do not contain starch, such as apple slices, carrots and sugar, for comparison. Test both a ripe and unripe banana, and notice that the unripe banana contains starch while the ripe banana does not.
