C-C, or C-C bond, refers to 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. C-C bonds can be single, double, or triple, depending on the number of shared electron pairs between the carbon atoms. The strength and stability of C-C bonds influence the properties of various compounds, including hydrocarbons and polymers. Understanding C-C bonding is essential for fields like biochemistry and materials science, as it helps in the design and synthesis of new materials and drugs.
