Ответ:
Unlike in beta-dicarbonyl compounds (which favors enol form) single keto group ketones are more stable in keto form.
For stability I searched for the bond energies. Below are the two forms. You can easily see the three different types of bonds and their energies. The main difference comes in the bond energy of C=O (carbonyl) group, which has the highest energy. Other energies are some what close to each other.
Remember: Greater the bond energies, greater will be the stability of compound.
Result:
The reason is "C=O bond is much stronger than C=C Bond".
