lodoform test It is used to check the presence of carbonyl compounds with the structure of

R - CO - C H_{3}

or alcohols with the structure

RC - H ∣ C H - C H_{3}

in a given unknown substance.
The reaction of iodine, a base and a methyl ketone gives a yellow precipitate along with an antiseptic smell.
