Two statements are given below.
Statement-I: In dry cleaning, the solvent \(\mathrm{Cl}_2 \mathrm{C}=\mathrm{CCl}_2\) was earlier used and now it is replaced by liquified \(\mathrm{CO}_2\)
Statement-II: In bleaching of paper, \(\mathrm{H}_2 \mathrm{O}_2\) was used earlier and now it is replaced by chlorine gas
Correct answer is
- A Statements I, II both are correct
- B Statements I, II both are incorrect
- C Statement I is correct but statement II is incorrect

Answer & Solution
Correct Answer
(C) Statement I is correct but statement II is incorrect
Step-by-step Solution
Detailed explanation
(I) Tetrachloroethene \(\left(\mathrm{Cl}_2 \mathrm{C}=\mathrm{CCl}_2\right)\) 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 \(\mathrm{CO}_2\) which result in less harm to…
