Maximum keto-enol tautomerism is shown by — Aldehydes Ketones and Carboxylic Acids Chemistry Question

💡 Solution & Explanation

Maximum Keto-enol tautomerism is shown by β- Keto-ester In this enol form is more stable due to formation of six membered cyclic (due to H-bonding) conjugated system. Carboxylic Acid and Its Derivatives 20 107. Which is more basic oxygen in an ester β O R C O R α (a) O denoted by (b) O denoted by (c) Both equally (d) None of the oxygen atoms is basic Due to resonance β oxygen is more basic
