Verified step by step guidance

Understand the concept of polarity: Polarity refers to the distribution of electrical charge around atoms, molecules, or chemical groups. Polar molecules have a partial positive charge on one side and a partial negative charge on the other, due to an uneven distribution of electrons.

Recognize the behavior of nonpolar molecules: Nonpolar molecules have an even distribution of electrical charge, meaning they do not have distinct positive or negative poles. This characteristic affects how they interact with water.

Learn about hydrophobic interactions: Nonpolar molecules tend to cluster away from water because they are hydrophobic, meaning 'water-fearing.' They do not dissolve well in water and prefer to associate with other nonpolar molecules.

Differentiate between hydrophilic and hydrophobic: Hydrophilic substances are 'water-loving' and interact well with water, often dissolving in it. Hydrophobic substances, on the other hand, avoid water and do not dissolve in it.

Apply the concept to the problem: Given the options, identify that nonpolar molecules that cluster away from water are called hydrophobic, as they do not interact favorably with water.
