WebMany halogenated hydrocarbons have important commercial applications. Alkyl halides are important intermediates in synthesis, as solvents in the laboratory and industry, and as dry cleaning fluids. They also find use as anesthetics and refrigerants. For example, trichloroethene is a common dry cleaning solvent. WebMar 9, 2024 · For example, methane (CH 4) can react with chlorine (Cl 2 ), replacing one, two, three, or all four hydrogen atoms with Cl atoms. Several halogenated products derived from methane and ethane (CH 3 CH 3) are listed in Table 1.7. 1, along with some of their uses. Table 1.7. 1: Some Halogenated Hydrocarbons.
