All about iodoform?
Iodoform has the chemical formula CHI3; it is a crystalline solid, volatile, yellow, with a characteristic odor. Iodoform was used as antiseptic.
What are the physical properties of iodoform at room temperature?
Iodoform is a solid at room temperature; the melting point is 119 0C, the density is approx. 4 g/cm3.
Why iodoform is used for functional group detection test?
Iodoform is used in the iodoform test to detect the presence of a methyl ketone functional group. When Iodoform reacts with a methyl ketone in the presence of a base and acidic conditions, it forms a yellow precipitate of iodoform, which confirms the presence of the CH3CO- group.
What are the uses of iodoform?
Iodoform is commonly used as an antiseptic for disinfecting wounds and preventing infections. It is also used in organic synthesis reactions as a reagent. Additionally, iodoform has historical uses in medicine as an analgesic and sedative.
Why cyclopentanone cannot undergo iodoform reaction?
Cyclopentanone cannot undergo the iodoform reaction because it lacks a methyl group attached to the carbonyl carbon that is necessary for the reaction to occur. The presence of a methyl group is essential for the formation of the triiodomethane (iodoform) product.

Why chloroform is in liquid state while iodoform is in solid state?
Chloroform is a small molecule with low molecular weight and forms a liquid due to weak intermolecular forces. Iodoform is a larger molecule with more atoms, leading to stronger intermolecular forces that result in a solid state at room temperature.

What happen when iodoform falls on skin or nails?
Iodoform is a disinfectant, pale yelow color.
What is hci3?
iodoform
What is the positive test for iodoform test?
Hi, Iodoform test is used for the detection of methyl ketones as methyl ketones give positive iodoform test. In this test, methyl ketone is treated with iodine (I2) in the presence of base such as sodium hydroxide (NaOH) to give iodoform(CHI3 - a light yellow coloured ppt). Chemistry of iodoform test is: Secondary alcohols also give positive iodoform test because during the reaction conditions, it gets oxidized to a methyl ketone.
What is the result of iodoform reacting with phenol?
When iodoform reacts with phenol, the iodoform is reduced to triiodomethane and phenol is oxidized to benzoquinone. The reaction results in the formation of a white precipitate of triiodomethane.
Will methanol give a positive result in iodoform test?
No, methanol will not give a positive result in the iodoform test. The iodoform test is specifically used to detect the presence of compounds with the CH3CO- group in them, such as methyl ketones, which are required for a positive reaction.
What purification method wa used in the experiment preparation of iodoform?
The purification method used in the preparation of iodoform in the experiment is recrystallization. This process involves dissolving the impure iodoform in a solvent at an elevated temperature and then slowly cooling the solution to allow pure iodoform crystals to form and separate from the impurities.
Is iodoform soluble in water?
Iodoform is sparingly soluble in water, meaning that only a small amount of it can dissolve in water.
