Concept explainers
(a)
Interpretation:
Resonance contributor for the enolate ion formed from the given compounds has to be identified.
Concept Introduction:
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 tautomers is the location of hydrogen and double bond.
Enol tautomer is much less stable than the keto tautomer.
Enol tautomer is more stable when enol tautomer is
Resonance: The delocalization of electrons which is characterized as several structural changes.

The only difference in keto-enol tautomers is the location of hydrogen and double bond.
Enol tautomer is much less stable than the keto tautomer.
Enol tautomer is more stable when enol tautomer is aromatic or when the double bonds are conjugated.
Resonance: The delocalization of electrons which is characterized as several structural changes.
