Which of the following reactions is characteristic of aldehydes? (2023)

Which of the following reactions is characteristic of aldehydes? (2023)

Step 1: Understand what aldehydes are. Aldehydes are organic compounds that contain a carbonyl group (C=O) at the end of a carbon chain.
Step 2: Learn about oxidation. Aldehydes can be oxidized, which means they can react with oxygen to form carboxylic acids.
Step 3: Learn about reduction. Aldehydes can also be reduced, which means they can react with hydrogen to form alcohols.
Step 4: Understand condensation with alcohols. Aldehydes can react with alcohols to form a new compound called a hemiacetal.
Step 5: Identify the reactions that are characteristic of aldehydes. The key reactions are oxidation to carboxylic acids, reduction to alcohols, and condensation with alcohols to form hemiacetals.
