(a)
Interpretation:
Enol tautomer of 2,4-pentanedione has to be drawn.
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.
(b)
