6 When the carbonyl group is located at the end of an organic molecule, to which ONE of the given homologous series does the molecule belong? A Alcohol B Aldehyde C Ketone D Haloalkane Which ONE of the follniwining

To determine the correct answer, let's analyze the options based on the position of the carbonyl group in the organic molecule: 1. **Alcohol**: This functional group contains a hydroxyl group (-OH) and does not have a carbonyl group. 2. **Aldehyde**: This functional group has a carbonyl group (C=O) located at the end of the carbon chain. Aldehydes are characterized by the presence of the carbonyl group at the terminal position. 3. **Ketone**: This functional group has a carbonyl group located within the carbon chain, not at the end. 4. **Haloalkane**: This functional group contains a halogen atom (like Cl, Br, I) attached to an alkane, and does not involve a carbonyl group. Given that the carbonyl group is located at the end of the organic molecule, the correct answer is: **B Aldehyde**.
