When comparing aldehydes and ketones, which statement is correct?

When considering the differences between aldehydes and ketones, one notable characteristic is the behavior of these compounds during oxidation. Aldehydes contain a carbonyl group (C=O) with at least one hydrogen atom attached to the carbonyl carbon, allowing them to be readily oxidized to carboxylic acids. Ketones, on the other hand, have two hydrocarbon groups attached to the carbonyl carbon and lack the hydrogen that makes aldehydes susceptible to oxidation.

The statement about ketones not being easily oxidized is based on this fundamental difference. Due to their structure, ketones are generally more stable and do not undergo oxidation as readily as aldehydes. Most ketones require more vigorous conditions for oxidation and typically do not convert to carboxylic acids like aldehydes do.

This understanding helps clarify why the assertion regarding the oxidation resistance of ketones distinctly identifies them from aldehydes and underscores the behavior of these compounds in various chemical reactions.
