Definition: A chemical compound that is a derivative of hydrogen peroxide, characterized by the presence of an OH group attached to a hydrocarbon chain.

Example: Hydroperoxide is often used as a bleaching agent in various industrial processes.

Definition: This word describes substances that are attracted to water and can easily mix with or dissolve in it.

Example: Sugar is hydrophilic, so it dissolves quickly in water.

Definition: A measure of how much a substance attracts and holds water molecules.

Example: The hydrophilicity of the material makes it ideal for use in wet environments.

Definition: Describing a substance that does not mix with water or repels it.

Example: The hydrophobic coating on the fabric keeps it dry in the rain.

Definition: The quality or condition of being repellent to water; substances with this property do not mix well with water.
