Which prefix indicates a chlorine substituent?

Explanation:
In naming organic compounds, substituent prefixes tell which group is attached to the main carbon skeleton. A chlorine substituent is indicated by the prefix chloro-. This shows chlorine replaces a hydrogen on the parent chain. For example, chloromethane has a chlorine attached to methane, and chlorobutane has chlorine on butane. The other prefixes correspond to different groups: bromo- for bromine, methyl- for a CH3 group, and ethyl- for a C2H5 group. So the prefix for a chlorine substituent is chloro-.
