Aldehydes can be synthesized by the oxidation of:
Correct answer: A. Primary alcohols
- A. Primary alcohols
- B. Secondary alcohols
- C. Organic acids
- D. Inorganic acids
Explanation
Consider any 1° alcohol. For simplicity consider it to be open-chain alcohol. There we find the Carbon atom directly attached to the -OH group has 2H atoms. And now oxidation occurs, one H gets removed from the Oxygen atom and the other H from the remaining 2.Thereby formation of a -HC=O, which is an Aldehyde. Again on oxidation of aldehydes, Oxygen gets attached to the Carbon directly attached to the -OH group thereby giving you carboxylic Acid. So basically oxidation is the main and the only factor which we find here and it is nothing but the removal of H atoms or addition of O atoms.

About Preparation of Aldehydes and Ketones
Aldehydes and ketones are prepared mainly by controlled oxidation or dehydrogenation of primary and secondary alcohols, respectively. The topic also includes ozonolysis of alkenes, hydration of alkynes and preparation through acyl derivatives, with attention to why primary alcohols can give aldehydes whereas secondary alcohols give ketones.
