Answer» Solution :Uses of green chemistry in our life is as below: (i) Dry Cleaning of Clothes : Tetra chlroroethene `(Cl_2 C = C CI_2)` was earlier used as solvent for dry cleaning. The compound contaminates the ground water and is also a suspected carcinogen. So insted of this compound liquefied carbondioxide with a suitable detergent is used. REPLACEMENT of halogenated solvent by liquid `CO_2` will result in LESS harm to ground water. Hydrogen peroxide `(H_2 O_2)` is used for the purpose of bleaching clothes which gives beller results and makes use of lesser amount of water. (ii) Bleaching of Paper : Earlier chlorine gas was used for bleaching paper whereas hydrogen peroxide `(H_2 O_2)` is used nowaday. (iii) Synthesis of Chemicals : Ethanal `(CH_3 CHO)` is now commercially PREPARED by oxidation of ETHENE in presence of ionic catalyst in aqueous medium with a yield of 90% `CH_2 = CH_2 + O_2 underset(Pd(II)//Cu(II) "(in water)")overset("Catalyst")to CH_3 CHO (90%)` |
