CH2CCH3CH2
CH2CCH3CH2 is a chemical formula that represents a molecule. This formula describes a structure containing carbon (C) and hydrogen (H) atoms. Specifically, it indicates two carbon atoms double-bonded to each other, a methyl group (CH3) attached to one of these carbon atoms, and another methylene group (CH2) attached to the other double-bonded carbon. The arrangement of these atoms creates a branched alkene. Alkenes are hydrocarbons that contain at least one carbon-carbon double bond. The presence of the double bond makes this molecule unsaturated and capable of undergoing addition reactions. This particular structure is known as 2-methylpropene, also commonly called isobutylene. Isobutylene is a colorless gas at room temperature and pressure. It is flammable and has a characteristic odor. It is an important industrial chemical used in the production of various polymers, such as polyisobutylene and butyl rubber. It also finds application as an intermediate in the synthesis of other organic compounds. Its reactivity is primarily associated with the carbon-carbon double bond.
