Refrigerants will decompose when exposed to high temperatures from flames or electric resistance heaters. Decomposition may produce toxic and irritating compounds, such as hydrogen chloride and hydrogen fluoride
Answer:
The correct answer is chlorine gas.
Explanation:
When HCFC and CFC or chlorofluorocarbons get exposed to ultraviolet light for a longer duration, they gradually get dissociate into chlorine radicals, as shown below:
CCl₃ ⇒ CCl₂F⁺ + Cl⁻
This Cl is not a molecule, however, is a radical, and thus, acts distinctly from Cl₂. The Cl⁻ reacts with O₃ (ozone) and reduces it to oxygen. Hence, depleting ozone present in the stratosphere, which safeguards life on Earth.
