What is meant by “hydrophobic” and “hydrophilic” in organic chemistry?

• A. Hydrophobic refers to compounds that mix well with water
• B. Hydrophilic refers to compounds that do not mix well with water
• C. Hydrophobic refers to compounds that do not mix well with water, while hydrophilic refers to compounds that do
• D. Both terms refer to the same type of compounds

Answer: (C)

In organic chemistry, the terms "hydrophobic" and "hydrophilic" describe the interaction of compounds with water. Hydrophobic compounds are characterized by their inability to mix with water, often due to their nonpolar nature. These compounds tend to repel water molecules and are more soluble in organic solvents. On the other hand, hydrophilic compounds have an affinity for water and can mix well with it, typically because they contain polar functional groups or ions that interact favorably with water. The distinction between the two is essential in understanding solubility, reactivity, and interactions in biological systems. For instance, this understanding is critical in the study of membrane structures, where hydrophobic tails of lipids form the inner layers away from water, while hydrophilic heads interact with the aqueous environment. The correct choice reflects this fundamental definition, clearly differentiating between the two classes of compounds based on their solubility in water. This understanding is pivotal in various applications, including pharmaceuticals, biochemistry, and material science, where the interactions of molecules in aqueous environments are crucial for their function and behavior.
