Final answer:
C) Both A and B. The correct answer to the question is C) Both A and B, as neither aldehydes nor ketones include organic acids and alcohol functional groups; they both contain a carbonyl group
Step-by-step explanation:
The question asks about organic structures that do not include organic acids and alcohols such as CH₃OH (methanol) and C₂H₅OH (ethanol). The options given are aldehydes and ketones, which are both groups of organic compounds containing the carbonyl group (-C=O). Aldehydes have the carbonyl group at the end of the carbon chain and are identified by the suffix '-al', while ketones have the carbonyl group within the carbon chain and use the suffix '-one'.
Neither aldehydes nor ketones are alcohols or organic acids; therefore, the correct answer to the question would be C) Both A and B. Unlike alcohols, which have an -OH group, neither aldehydes nor ketones include this moiety. Additionally, both aldehydes and ketones typically have lower boiling points compared to alcohols and do not exhibit the acidic properties associated with organic acids.
