Question “Addition of water to an alkyne gives a keto-enol tautomer product. Draw an enol that is in equilibrium with the given…”
Addition of water to an alkyne gives a keto-enol tautomer
product. Draw an enol that is in equilibrium with the given
ketone.
Answer
If a compound with ketone functional groups is given, the enol form must be drawn. The migration of hydrogen atoms in the structure is what forms tautomer. Form the enol-tautomer of the given ketone molecule through the migration of H from the carbon atom.
The migration of hydrogen atoms from adjacent carbon atoms in the structure creates Tautomer. Tautomer inter-convert easily into each other and there is always an equilibrium between them. The following compound is showing keto-enol automer:
