The triiodomethane (iodoform) reaction can be used to identify the presence of secondary alcohols. 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): CHI3, which apart from its color, can also be recognized by its faintly "medical" smell. It is used as an antiseptic on the sort of sticky plasters you put on minor cuts.
**Explain the mechanism of iodoform reaction in an assumption that the iodine/sodium hydroxide solution was used for the reaction. Provide a figure or schematic diagram for the complete detailed flow of reaction.
