The correct Answer is:
To determine which of the statements about aldehydes and ketones is correct, let's analyze each statement one by one. ### Step 1: Analyze Statement I **Statement I:** Aldehydes are generally oxidized under vigorous conditions. **Analysis:** Aldehydes (RCHO) can be oxidized to carboxylic acids (RCOOH). This oxidation can occur under mild conditions, such as using mild oxidizing agents like Tollens' reagent or Fehling's solution. Therefore, this statement is **false**. ### Step 2: Analyze Statement II **Statement II:** Ketones are easily oxidized to carboxylic acids even under mild oxidizing agents. **Analysis:** Ketones (RC(=O)R') are generally more resistant to oxidation compared to aldehydes. They typically require stronger oxidizing agents and more vigorous conditions to oxidize to carboxylic acids. Therefore, this statement is also **false**. ### Step 3: Analyze Statement III **Statement III:** Oxidation of ketones involves carbon-carbon bond cleavage, giving a mixture of carboxylic acids having a lesser number of carbon atoms than the parent ketones. **Analysis:** When ketones undergo oxidation, especially under strong conditions, they can indeed undergo carbon-carbon bond cleavage. This results in the formation of smaller carboxylic acids, which have fewer carbon atoms than the original ketone. Therefore, this statement is **true**. ### Conclusion Based on the analysis: - Statement I is false. - Statement II is false. - Statement III is true. Thus, the correct answer is that **only Statement III is correct**. ### Final Answer **The correct option is Statement III.** ---

Which alcohol on oxidation gives ketones as well as acid containing lesser number of carbon atoms than parent alcohol ?

Aldehydes and ketones undergo nucleophilic addition reactions. With weak nucleophiles such as ammonia and its derivatives, (H_2 N-Z) , aldehydes and ketones react in weakly acidic medium to form compounds containing carbonnitrogen double bond with the elimination of water to form . Aldehydes can be easily oxidised to carboxylic acid on treatment with common oxidising agents like KMnO_4 K_2 Cr_2 O_7 , HNO_3 , etc. The carboxylic acid formed contain the same number of carbon atoms as the aldehydes. However ketones under drastic conditions with powerful oxidising agents undergo cleavage of C-C bond giving mixture of carboxylic acids having lesser number of C atoms than the original ketone. Write the reaction of acetone with semicarbazide.
