Final answer:
Cyclohexanol is more soluble in water than cyclohexanone because it can form hydrogen bonds due to its hydroxyl group.
Step-by-step explanation:
The solubility of organic compounds often depends on their ability to participate in hydrogen bonding. Cyclohexanol is more soluble in water due to its ability to form hydrogen bonds. This is because cyclohexanol contains a hydroxyl group (-OH) capable of forming hydrogen bonds with water molecules.
On the other hand, cyclohexanone, though it has a polar carbonyl group, lacks hydrogen-bond donor atoms, reducing its solubility in water compared to cyclohexanol. Hence, the correct answer is cyclohexanol; due to hydrogen bonding.
