Pyridine waste is halogenated.

• A. Not applicable
• B. False
• C. Not sure
• D. True

Answer: (B)

Understanding whether a waste is halogenated depends on the presence of halogen atoms (fluorine, chlorine, bromine, or iodine) in the substance. Pyridine itself has the formula C5H5N, containing only carbon, hydrogen, and nitrogen—no halogens. Therefore, pyridine waste without any halogen-containing contaminants is not halogenated. The statement is false because the compound itself does not include halogen atoms. If the waste were contaminated with halogenated materials, it could become halogenated, but pure pyridine waste is not.
