Which option correctly identifies a halogenated waste?

• A. Waste containing toluene
• B. Waste containing Acetone
• C. Waste containing Dichloromethane
• D. Waste containing Ammonia

Answer: (C)

Halogenated waste contains compounds that have halogen atoms (like chlorine, bromine, fluorine, or iodine) attached to carbon. This often makes the waste more hazardous and requires special disposal.

Toluene and acetone are organic solvents that do not contain halogen atoms, so they are not halogenated wastes. Ammonia is inorganic and also does not contain halogens. Dichloromethane, on the other hand, has chlorine atoms in its structure, making it a halogenated solvent and thus halogenated waste.
