Which of the following statements are correct regarding the chemical tests for carbonyl compounds an — Practical Organic Chemistry and Purification Chemistry Question

💡 Solution & Explanation

Tollen's reagent is reduced by both aliphatic and aromatic aldehydes. Fehling's solution is weaker and is only reduced by aliphatic aldehydes (aromatic aldehydes fail). $\alpha$ -hydroxy ketones and formic acid are standard exceptions that contain oxidizable structures, allowing them to give positive results with Tollen's reagent and Fehling's solution.
