What is the iodoform test for alcohols?
Iodoform test for alcohol
Iodoform Test can be used to identify the presence of carbonyl compounds group in alcohols. The reaction of Iodine along with the base with methyl ketones results in the appearance of a very pale yellow precipitate of triiodomethane (previously known as iodoform).What is the indication of a positive iodoform tests for alcohols?
Indications of a positive test:
The formation of a yellow precipitate or suspension of iodoform is a positive test.How do you show ethanol in iodoform test?
Ethanol forms acetaldehyde on oxidation, so it gives the iodoform test. The formation of a pale yellow precipitate when iodine in sodium hydroxide reacts with alcohol that can be oxidized to acetaldehyde is the iodoform reaction.- The iodoform test is used to identify secondary alcohols that have a methyl group on the alcohol carbon. This type of alcohol will react with I2 in NaOH to give a yellow precipitate of iodoform, CHI3.
