what does iodoform test indicate
Iodoform Reaction. The iodoform test indicates the presence of an aldehyde or ketone in which one of the groups directly attached to the carbonyl carbon is a methyl group. Such a ketone is called a methyl ketone. In the iodoform test, the unknown is allowed to react with a mixture of iodine and base.Hydrogens alpha to a carbonyl group are acidic and will react with base to form the anion, which then reacts with iodine to form an alpha-iodo ketone.uch a ketone is called a methyl ketone.
