The correct answer is C. Acetic acid.
Acetic acid is a chemical compound with the formula CH3COOH. It is a colorless liquid that is miscible with water and has a distinctive sour taste and pungent odor. Acetic acid is produced naturally by fermentation of sugars and starches. It is also produced synthetically by carbonylation of methanol.
Acetic acid is the main component of vinegar, and it is used in a variety of other products, including food, beverages, cosmetics, and pharmaceuticals. It is also used in the production of plastics, fibers, and other chemicals.
Acetic acid is a weak acid, and it is a good solvent for many organic compounds. It is also a corrosive agent, and it can cause burns to the skin and eyes.
The other options are incorrect because they do not have the -OH functional group.
- Carbonyl acid is a general term for any compound that contains a carbonyl group, which is a carbon atom double-bonded to an oxygen atom.
- Ethanoic acid is the IUPAC name for acetic acid.
- Butanol is a four-carbon alcohol with the formula C4H9OH.
