One of the following is application of iodoform reaction:
Correct answer: B. Carboxylic acid are formed by methyl ketones
- A. Iodine is separated from reaction mixture
- B. Carboxylic acid are formed by methyl ketones
- C. Ketone are formed from this reaction
- D. Identification of methanol
Explanation
One of the applications of the iodoform reaction is in the formation of carboxylic acids from methyl ketones. In this reaction, a methyl ketone reacts with iodine in the presence of a base, such as sodium hydroxide (NaOH). The reaction results in the formation of a yellow precipitate called iodoform (CHI3) and a carboxylic acid. This reaction is a way to identify the presence of a methyl ketone and can be used in organic chemistry laboratories.

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
