(a)
Interpretation:
Enol tautomer of the given compound has to be drawn.
Concept Introduction:
Keto-Enol tautomerization: The enol and keto are said to be tautomer, are constitutional isomers that rapidly interconvert via the migration of a proton. The interconversion between an enol and a
The tautomerization is catalyzed by even trace amounts of acid (or base).
Tautomerism is the ability of a molecule to exist in more than one chemical form. Tautomers are formed by the migration of a hydrogen atom, accompanied by the switching of a single and neighboring double bond.
The only difference in keto-enol tautomer is the location of hydrogen and double bond.
(b)
Interpretation:
Enol tautomer of the given compound has to be drawn.
Concept Introduction:
Keto-Enol tautomerization: The enol and keto are said to be tautomer, are constitutional isomers that rapidly interconvert via the migration of a proton. The interconversion between an enol and a ketone is called keto-enol tautomerization. Tautomerization is an equilibrium process, that the equilibrium will establish specific concentrations for both the enol and the ketone. Once the equilibrium is reached, the concentrations of ketone and enol can be measured.
The tautomerization is catalyzed by even trace amounts of acid (or base).
