Two statements are given below. Statement-I: In dry cleaning, the solvent Cl ₂ C = CCl ₂ was earlier used and now it is replaced by liquified CO ₂ Statement-II: In bleaching of paper, H ₂ O ₂ was used earlier and now it is replaced by chlorine gas Correct answer is
Options
- AStatements I, II both are correct
- BStatements I, II both are incorrect
- CStatement I is correct but statement II is incorrect
- DStatement I is incorrect but statement II is correct
Correct answer
C. Statement I is correct but statement II is incorrect
Step-by-step solution
(I) Tetrachloroethene ( Cl ₂ C = CCl ₂ ) was earlier used as solvent for dry cleaning. The compound contaminates the ground water and is also a suspected carcinogen. Now it is replaced by liquid CO ₂ which result in less harm to ground water. (II) H ₂ O ₂ is used for purpose of bleaching clothes in the process of laundry, which gives better result and makes use of lesser amount of water.
