IODOFORM TEST FOR ALCOHOL - DEFINITION

The triiodomethane (iodoform) reaction can be used to identify the presence of a CH

CH(OH) group in alcohols. There are two apparently quite different mixtures of reagents that can be used to do this reaction, but are chemically equivalent. This is chemically the more obvious method. Iodine solution is added to a small amount of an alcohol, followed by just enough sodium hydroxide solution to remove the color of the iodine. If nothing happens in the cold, it may be necessary to warm the mixture very gently. A positive result is the appearance of a very pale yellow precipitate of triiodomethane (previously known as iodoform): CHI

Answer:

The iodoform test is a test for the presence of carbonyl compounds with the structure

RCOCH3 and alcohols with the structure

RCH(OH)CH3

Explanation:

A solution of I2 is added to a small amount of your unknown, followed by just enough

NaOH to remove the colour.

The formation of a pale yellow precipitate of iodoform (with a characteristic "antiseptic" smell) is a positive result.
