Answer:
True
Step-by-step explanation:
When Chlorinated hydrocarbon is exposed to extremely high temperature (be it ultraviolet radiation), phosgene (COCl2) is produced. These chlorinated hydrocarbon compounds are produced in industries for various usages in paints, metal cleaning, etc. and primarily consists of carbon, hydrogen and chlorine. Phosgene can be produced by various other ways such as a) Treating CHCL3 by chromic acid mixture, b) reaction of CCl4 and oleum etc.
Hence, the statement "Phosgene is a chemical agent that is formed by decomposition of chlorinated hydrocarbon solvents by ultraviolet radiation." is true
