Verified step by step guidance

Understand the term 'hydrophobic': In chemistry, 'hydrophobic' refers to the property of a molecule that is repelled by water. These substances do not mix well with water and tend to separate from it.

Identify the characteristics of hydrophobic substances: Hydrophobic substances are typically nonpolar, meaning they do not have a charge distribution that allows them to interact favorably with water molecules, which are polar.

Consider the behavior of hydrophobic substances in water: Since hydrophobic substances do not dissolve in water, they tend to repel water molecules and do not form hydrogen bonds with them.

Evaluate the given options: Compare each option to the characteristics of hydrophobic substances. A hydrophobic substance should not dissolve in water, should repel water, and should not form hydrogen bonds with water.

Select the correct description: Based on the understanding of hydrophobic substances, choose the option that states 'A substance that repels water and does not dissolve in it' as it aligns with the definition of hydrophobic.
