Cyclobutane is a cyclic hydrocarbon with the chemical formula C₄H₈. It consists of four carbon atoms arranged in a square shape, with each carbon atom bonded to two hydrogen atoms. This unique structure gives cyclobutane distinct properties compared to other hydrocarbons. Due to its ring structure, cyclobutane is less stable than larger cycloalkanes, making it more reactive. It can undergo various chemical reactions, including ring-opening reactions, which are important in organic synthesis. Cyclobutane is used in research and has potential applications in the development of new materials and pharmaceuticals.
