What is Idoform?

What is Idoform?

The iodoform test or reaction is a chemical reaction where iodoform is produced by the multiple halogenations of a methyl ketone (a molecule which contains R-CO-CH3 group) in the presence of a base. R can be H, alkyl or aryl group.

What type of reaction is Iodoform?

Iodoform reaction: A chemical reaction in which a methyl ketone is oxidized to a carboxylate by reaction with aqueous HO- and I2. The reaction also produces iodoform (CHI3), a yellow solid which may precipitate from the reaction mixture.

What is Iupac name of Iodoform?

Iodoform (also known as triiodomethane and, inaccurately, as carbon triiodide) is the organoiodine compound with the formula CHI3….Iodoform.

Preferred IUPAC name Triiodomethane
Other names Iodoform; Carbon triiodide
CAS Number 75-47-8

What is Iodoform use?

Iodoform, also called triiodomethane, a yellow, crystalline solid belonging to the family of organic halogen compounds, used as an antiseptic component of medications for minor skin diseases.

How is iodoform prepared explain properties and uses?

Preparation and properties of iodoform It is manufactured by the electrolysis of aqueous solution containing acetone, inorganic iodides and sodium carbonate. Iodoform is also known as tri-iodomethane, carbon tri-iodide and methyl tri-iodide. The names are due to the presence of three iodine molecules in the compound.

What is the smell of iodoform?

A pale yellow, crystalline, volatile substance, it has a penetrating and distinctive odor (in older chemistry texts, the smell is sometimes referred to as the smell of hospitals, where the compound is still commonly used) and, analogous to chloroform, sweetish taste.

What causes positive iodoform?

A positive result – the pale yellow precipitate of triiodomethane (iodoform) – is given by an aldehyde or ketone containing the grouping: Lots of ketones give this reaction, but those that do all have a methyl group on one side of the carbon-oxygen double bond. These are known as methyl ketones.

What is the chemical name of NaI?

Sodium iodide (NaI) is a water soluble ionic compound that consists of an equivalent addition of sodium as a cation (Na+) and iodide as an anion (I-) in crystal space. It is industrially prepared by reacting acidic iodides with sodium hydroxide (NaOH) to form NaI salts.

Is iodoform still used?

Abstract. Iodoform (triiodomethane), a yellow crystalline solid, belonging to the family of organic halogen compounds, is used as an antiseptic. Its antiseptic action is due to the slow release of iodine under the action of catalase from wounds. Currently, it is widely used only in dentistry and in veterinary medicine.

What is effect of iodoform?

* Breathing Iodoform can irritate the nose and throat. * Exposure to high levels can affect the nervous system causing confusion, irritability, headache, hallucinations and/or poor muscle coordination. * Iodoform may cause a skin allergy. If allergy develops, very low future exposure can cause itching and a skin rash.

What is meant by iodoform test?

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).
