Metüleenrühm

Metüleenrühm is the common name for the chemical group derived from methane by replacing two hydrogen atoms with other groups. Its chemical formula is typically represented as CH2. This functional group is a key component in many organic compounds. It is characterized by a carbon atom bonded to two hydrogen atoms and two other substituents. The presence of the metüleenrühm can significantly influence the physical and chemical properties of a molecule. For example, it is found in polymers like polyethylene, where repeating metüleen units form the polymer backbone. In the context of organic synthesis, the metüleenrühm can participate in various reactions, acting as a linker between different parts of a molecule or as a site for further chemical modification. Its electronic structure and bonding arrangement contribute to its reactivity and stability within a larger molecular framework. The term is widely used in organic chemistry to describe this specific divalent carbon unit.
