Halogenated derivatives of hydrocarbons
In plain English
This category covers chemical compounds made by adding halogens to hydrocarbons, which are divided based on whether the base hydrocarbon is straight-chain, ring-shaped, or aromatic. Straight-chain versions are further split into saturated or unsaturated types, with specific groups for chlorinated, fluorinated, brominated, iodinated, or mixed-halogen derivatives. Ring-shaped hydrocarbons are categorized separately, as are aromatic hydrocarbons, with each group listing specific named chemicals before including a catch-all for other items not explicitly listed.
