CH3CHCH

CH3CHCH is a chemical formula that represents an organic molecule. It is a representation of a hydrocarbon containing three carbon atoms and six hydrogen atoms. The arrangement of these atoms is implied by the formula. The "CH3" group indicates a methyl group, which is a carbon atom bonded to three hydrogen atoms. The "CH" group indicates a carbon atom bonded to one hydrogen atom. The final "CH" is typically understood to be part of a double bond in this context, with the two carbon atoms sharing a pair of electrons, making it an alkene. Therefore, CH3CHCH most accurately describes propene, also known as propylene, which has the structure CH3-CH=CH2. Propene is a colorless gas with a faint petroleum-like odor. It is a significant petrochemical produced by the steam cracking of hydrocarbons. Its primary use is as a monomer in the production of polypropylene, a widely used plastic. It also serves as a feedstock for other chemical syntheses, including the production of propylene oxide and cumene.
