Chemistry : Air conditioner refrigerant fluids

This is a photograph of a tank of refrigerant fluid used by a repairman to recharge old air conditioners and refrigerators.

The liquified gas in the tank is Chlorodifluoromethane [Link to wikipedia article] which is a formed by allowing chlorine and fluorine atoms to replace hydrogen atoms in the methane molecule in a textbook reaction known as substitution.
