Learn how to perform the iodoform test to identify methyl ketones, acetaldehyde and some secondary alcohols with a methyl group in alpha position. See the reaction mechanism, examples, FAQs and a quiz on this topic.
- The only primary alcohol that provides the triiodomethane (iodoform) reaction is ethanol. If ‘R’ is a category of hydrocarbons, you have a secondar...
- The iodoform test reveals the presence of an aldehyde or ketone in which a methyl group is one of the groups immediately connected to the carbonyl...
- The methyl ketone reaction of iodine and base is so reliable that the iodoform test (the appearance of a yellow precipitate) is used to test for me...
- For 3 ml of water and 10 drops of KI / I2 solution (a dark purple-brown solution), three drops of the compound to be evaluated are applied. Until t...
- Methyl ketones and secondary alcohols oxidizable to methyl ketones, such as isopropanol, are commonly limited by substrates. Ethanol and acetaldehy...

May 15, 2023 · Learn how to perform the iodoform test to identify carbonyl compounds and alcohols with a methyl group in the alpha position. Find out the reaction mechanism, examples, and FAQs about this test.
- Any chemical containing carbonyl compounds with the structural formula \(R-CO-CH_{3}\) or alcohols with the formula \(R-CH(OH)-CH_{3}\).
- The compounds that do not have a methyl group directly connected to a carbonyl group (acyl) will not give the iodoform test.
- Yes, ethanol gives an iodoform test as it contains a methyl group directly attached to the alpha carbon.
- Yes, acetaldehyde is the only aldehyde that gives a positive iodoform test.
- Resorcinol, Phouroglucinol, nitromethane, etc, are the exceptions for the iodoform test because these compounds do not follow the general criteria...
