Physical and Chemical Properties of Aldehydes/Ketones & Tollens' Test OBJECTIVES 1. To investigate the physical properties and uses of some common aldehydes and ketones. 2. To develop familiarity with reaction of aldehydes which are of particular importance in biochemistry. 3. To learn to use characteristic reactions to distinguish between aldehydes and ketones, and between aliphatic and aromatic aldehydes. PRE-LABORATORY QUESTIONS Complete as assigned. 1. Find the structures of ethanal (acetaldehyde) and acetone. Draw the full structure for each compound and classify each as either an aldehyde or ketone. 2. How is a positive Tollens' test indicated? 3. Choose one of the compounds from the text or today's lab that would react with Tollens' Reagent and write a chemical equation for this reaction. Use full structures for any organic compound. lest ection 13
