Question
Chapter 9, Problem 62IP
Interpretation Introduction
Interpretation: For the given set of molecules the keto-enol tautomerism should be identified.
Concept Introduction:
Tautomerism: The two isomer of compound which differ only in the position of the protons and electrons. In the carbon skeleton of the compound is unchanged, a reaction which involves simple proton transfer in an intramolecular fashion it is called a tautomerism.
Keto-enol tautomerism: This is common process and is acid or base catalyst. Typically the keto from the compound is more stable, but in some instance the enol form can be the more stable.
