Answer: the correct option is (C)
Explanation:
1) In a organic molecules there are two types of parts in a molecule:
- Hydrophilic part which interacts with water molecule through hydrogen bonding.If this part is present in large proportion then the organic molecule will be more soluble in water. Here hydrophilic part is (-OH) group in the molecules.
- Hydrophobic part which do not interact with water molecule.If this part is present in large proportion then the organic molecule will be insoluble in water. Here hydrophobic part is carbon chain present in the molecules.
So, the most soluble molecule in the water will be:
