Chemistry question: Addition of water to an alkyne gives a keto-enol tautomer product. Draw an enol that is in equilibrium with the given ketone.
Addition of water to an alkyne gives a keto-enol tautomer product. Draw an enol that is in equilibrium with the given ketone. Addition of water to an alkyne gives a keto-enol tautomer product. Draw an enol that is in equilibrium with the given ketone.
Solution:
Concepts and reason
A compound containing ketone functional group is given, its enol form needs to be drawn. Generally, tautomer is formed by the migration of hydrogen atom in the structure. Thus, form the enol tautomer of the given ketone molecule by the migration of H atom from the adjacent carbon atom.
Fundamentals
Tautomer is formed by the migration of hydrogen atom from the adjacent carbon atom in the structure. Tautomer readily inter-convert into one another and there is always a dynamic equilibrium between them. Consider the following compound that is showing keto-enol tautomer.
