Where are covalent bonds often found?

Covalent bonds are commonly found in molecular compounds, where atoms share pairs of electrons to achieve stability. They are prevalent in organic molecules, such as carbohydrates, proteins, and nucleic acids, as well as in inorganic compounds like water (H₂O) and carbon dioxide (CO₂). These bonds are essential for the structure and function of biological macromolecules and play a crucial role in the chemistry of life.
