Correct option is A

The correct answer is (a) Propanone.
· The IUPAC (International Union of Pure and Applied Chemistry) name for CH₃COCH₃ is Propanone. This compound is the simplest ketone, consisting of three carbon atoms with a carbonyl group (C=O) located between two methyl groups.
· In IUPAC nomenclature, ketones are named by replacing the "-e" of the corresponding alkane (propane) with "-one," indicating the presence of the carbonyl group.
· It is commonly known as acetone, a well-known solvent used in various industries.
· Propanone is the simplest member of the ketone family.
· It is a colorless, volatile liquid with a characteristic odour.
· Ketones are named in IUPAC by identifying the longest carbon chain and numbering the carbon atoms such that the carbonyl group gets the lowest possible number.
· Acetone (propanone) is miscible with water and used as a cleaning agent and in nail polish removers.
Additional Knowledge:
· Acetone: This is the common name for propanone. While it describes the same compound, it is not the IUPAC name.
· Propane: This is an alkane with three carbon atoms and no carbonyl group. It is not related to ketones.
· Dimethyl ketone: This is another common name for propanone, describing its structure (two methyl groups attached to a ketone), but it is not the official IUPAC name.
