Question

Chlorofluorocarbons; CF2Cl2 Hydrochlorofluorocarbons: HCF2Cl Which functional group does each chemical belong to and why. Explain.

How does the type of bonding and functional group these molecules posses affect their reactivity?

What are the health and environmental effects of the two chemicals?

Take one of the chemicals above and discuss and explain the properties of that chemical (such as water solubility, vapor pressure, etc.) that determines its migration in our environment.

Name one green chemistry principle that could have the greatest potential to minimize the future impact of each of the two chemicals you discussed, explaining how each green chemistry principle can be applied specifically to each chemical.

Explanation / Answer

Functional group: Hydrochlorofluorocarbons and Chlorofluorocarbons belong to alkyl halide group.

As in simpler alkanes, carbon in the CFCs bonds with tetrahedral symmetry. Because the fluorine and chlorine atoms differ greatly in size and effective charge from hydrogen and from each other, the methane-derived CFCs deviate from perfect tetrahedral symmetry.

CF2Cl2 is responsible for ozone depletion in stratosphere which makes ultraviolet rays reach earth and they penetrate through human body causing skin cancer.
