Soaps and detergents are kept in the family of which of the following types of compounds?

Correct answer: A. Surface active

  • A. Surface active
  • B. Surface inactive
  • C. Water soluble
  • D. Water insoluble

Explanation

Soaps and detergents are surface-active agents, also known as surfactants. They possess both hydrophilic (water-attracting) and hydrophobic (water-repelling) parts in their molecular structure. This dual nature allows them to interact with both water and oil, enabling them to act as cleansing agents that emulsify and lift away dirt and grease from surfaces.

About Biological Molecules

The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
