Aldehydes are obtained by the oxidation of which of the following?
Correct answer: D. Primary alcohols
- A. Secondary alcohols
- B. Tertiary alcohols
- C. Dihydric alcohols
- D. Primary alcohols
Explanation
Aldehydes can be obtained by the oxidation of primary alcohols. Primary alcohols, when oxidized, are first converted into aldehydes. Further oxidation of aldehydes leads to carboxylic acids. Therefore, option d is correct.

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
