    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

    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.
