Question

B. Aldehydes are oxidized to alcohols.
C. Aldehydes are oxidized to ketones.
D. Aldehydes are oxidized to carboxylic acids.

Common mistake

Confusing Aldehydes and Ketones

Students often confuse aldehydes with ketones, thinking both can be oxidized to carboxylic acids.

Remember that only aldehydes can be oxidized to carboxylic acids, while ketones cannot. Use the structure of the carbonyl group to identify them: aldehydes have the carbonyl group at the end of the carbon chain, while ketones have it within the chain.
