CHCHBr

CHCHBr is a chemical formula that can represent a few different molecular structures, all of which contain carbon (C), hydrogen (H), and bromine (Br). The most common interpretation of CHCHBr is likely ethenyl bromide, also known as vinyl bromide. This molecule has the structure CH2=CHBr, where a double bond exists between two carbon atoms, and one of these carbon atoms is bonded to a bromine atom and two hydrogen atoms, while the other carbon atom is bonded to one bromine atom and two hydrogen atoms. Vinyl bromide is a colorless gas with a sweet odor and is highly flammable. It has been used in the past as a monomer for the production of polymers, but its use has been significantly restricted due to its carcinogenic properties.

Another possibility for CHCHBr is dibromoethane isomers. For example, 1,1-dibromoethane (CH3CHBr2) or 1,2-dibromoethane (CH2BrCH2Br). 1,1-dibromoethane has a bromine atom attached to each of two adjacent carbon atoms, with one carbon having two hydrogens and the other having three. 1,2-dibromoethane has one bromine atom attached to each of two adjacent carbon atoms, with each carbon also bonded to two hydrogen atoms. These compounds are liquids with distinct odors and have various industrial applications, including as solvents and intermediates in chemical synthesis, though safety concerns and regulatory restrictions are also associated with them. The specific isomer intended by CHCHBr would require further context.
