Compounds containing carbon are exceptionally stable due to the strength and versatility of carbon-carbon bonds. Carbon forms strong sigma (σ) bonds in various configurations (single, double, or triple bonds) and is capable of creating stable, complex molecular structures. The small size of carbon allows for effective orbital overlap, enhancing the strength of covalent bonds. Additionally, the ability to form multiple bonds and diverse functional groups contributes to the stability and reactivity of carbon compounds. This stability is crucial for the formation and existence of complex organic molecules, making carbon-based compounds fundamental to the stability of biological systems and various industrial applications.
