A C-C bond, or carbon-carbon bond, is a type of chemical bond that occurs between two carbon atoms. This bond is fundamental in organic chemistry, as it forms the backbone of many organic molecules, including hydrocarbons and biomolecules. C-C bonds can be single, double, or triple, depending on how many pairs of electrons are shared between the carbon atoms. The strength and stability of C-C bonds vary based on their type. Single C-C bonds are generally weaker than double or triple bonds, which involve more shared electron pairs. Understanding C-C bonds is essential for studying the structure and reactivity of organic compounds, including those found in proteins, lipids, and carbohydrates.
