Which of the following is used as water disinfectant to avoid the formation of toxic compounds_________________?
Correct answer: D. both B & C
- A. Cl2
- B. O3
- C. ClO2
- D. both B & C
Explanation
Ozone and chlorine dioxide are effective water disinfectants and do not produce the chlorinated organic by-products associated with ordinary chlorine treatment to the same extent. Chlorine gas is the likely wrong choice because it is a traditional disinfectant but can form harmful chlorinated compounds.

About Real and Ideal Gases
An ideal gas is modelled as particles with negligible volume and no intermolecular attraction, obeying Boyle's, Charles's and Avogadro's laws through PV = nRT. Real gases deviate from this behaviour, especially at high pressure and low temperature, because particle volume and attractive forces matter; the van der Waals equation explains these corrections.
