# Addition of water to an alkyne gives a keto-enol tautomer product. What will be the enol that is in equilibrium with the given ketone 2-Pentanone?

What do you think would happen to the enol hydrogens if the parent ketone were involved in an equilibrium with D^(+)"/"D_2O" "(D=""^2H)? Could deuterium be incorporated on the backbone of the ketone?
