Answer» Solution :A numbe rof polyhalogen coompounds, e.g., dichloromethane, CHLOROFORM, iodoform, carbon tetrachloride, FREON and DDT have many applications in our daily LIFE. Freions also cause depletion of ozone layer and thus allow more UV rays to reach the earth which, in turn, damage flora and fauna. to minimise the harmful effects of freons, hydrofluorocarbons and fluorocarbons which are stable in the STRATOSPHERE should be used in aerosol propellants and in air conditioning equipments.
