Hexane-2,4-dione has a higher enol content in hexane than in water. This is because

1. Awater forms hydrogen bonds with the enol more strongly than with the keto form, but hexane does not
2. Bhexane reacts with the keto form and removes it
3. Cthe chelated cis-enol is less polar than the diketo form, so a non-polar solvent favours it while water stabilises the polar diketo form
4. Dthe enol content is the same in all solvents because $K_T$ depends only on temperature
