Explanation / Answer

11. Keto–enol tautomerism is a phenomenon where a chemical equilibrium exists between a keto form and an enol (an alcohol). This happens as a result of the movement of an alpha hydrogen and the shifting of bonding electrons. Among given structures, all of them satisfy the conditions for keto-enol isomerism.

Thus option e is the correct answer.

As per the policy of Chegg, only one question is answered. Answers to few questions are given without explanation

12. In this molecule, those carbons attached to F or Br are stereocenters. Both of them are of R configuration

13. (R,E)-2-Chlorohex-2-ene

14. The structure with the removal of a proton from COOH group. conjugate base exists as -COO- . All other groups remain as such.

15. The corresponding alcohol will be formed O- will become -OH
