Academics

Chlorofluorocarbons (CFCs) were introduced as refrigerants in the 1930s, replacing other gases that were toxic and corrosive. How do the molecular shape and polarity of CFCs contribute to the many desirable qualities they have as refrigerants? Given that they are such desirable refrigerants, why are they banned? What chemistry is involved? How has their molecular shape and polarity had harmful effects on the atmosphere?
