Question

How does the type of bonding and functional group of Chlorofluorocarbons; CF2Cl2 and Hydrochlorofluorocarbons: HCF2Cl molecules posses affect their reactivity?

Answer 1

Chlorofluorocarbons CF2Cl2 are non-polar or less polar molecules due to the symmetry in the structure of the moelcule than the hydrochlorofluorocarbons. The reactivity of hydrochloroflurocarbons is thus higher than chlorofluorocarbons and is thus an effective and most used alternative to chlorofluorocarbons. Due to the high reactivity of hydrochlorofluorocarbons as compared to chlorofluorocarbons, hydrochlorofluorocarbons tend to decompose in the atmosphere before it reaches the stratosphere and thus do not causes harm to the ozone layer as like chlorofluorocarbons.
