Iodoform test is used to check the presence of carbonyl compounds with the structure R-CO-CH 3 or alcohols with the structure R-CH OH-CH 3 in a given unknown substance. A positive result - the pale yellow precipitate of triiodomethane iodoform - is given by an aldehyde or ketone containing the grouping R can be a hydrogen atom or a hydrocarbon. Sodium chlorate I solution is alkaline and contains enough hydroxide ions to carry out the second half of the reaction The reason that sodium chlorate I is. A solution of iodine left ceI_2 right and iodide left ceI- right in ceNaOH can be used to test for methyl ketones or secondary alcohols adjacent to a methyl group. The triiodomethane iodoform reaction can be used to identify the presence of a CH 3 CH OH group in alcohols There are two apparently quite different mixtures of..
