Solution
Correct Answer:
-CO-
Ketones are characterized by the Carbonyl group (−C=O) bonded to two other carbon atoms (R−CO−R′).
- Other groups:
- −CHO: Aldehyde (Carbonyl at the end of a chain).
- −COOH: Carboxylic Acid.
- −OH: Hydroxyl (Alcohol).
- General formula for aliphatic ketones: CnH2nO (starting from n=3, Propanone).
This easy difficulty chemistry question is from the chapter some basic principles of organic chemistry, covering the topic of functional groups. It appeared in the 2025 exam.
