Which reaction among the following gives nascent oxygen?
Options
- ANa ₂ SO ₃+ Cl ₂ H ₂ O
- BNaOH + Cl ₂
- CCa ( OH )₂+ Cl ₂
- DCl ₂+ H ₂ O
Correct answer
D. Cl ₂+ H ₂ O
Step-by-step solution
When chlorine react with water, it gives HCl and oxygen. Chlorine Cl ₂ + Water H ₂ O 2 HCl +[ O ] While other reactions take place as follows : Sodium thiosulphate Na ₂ ~S ₂ O ₃(a q) + Cl ₂+ H ₂ O Sulphur S + Sodium sulphate Na ₂ SO ₄ +2 HCl Sodium hydroxide NaOH + Cl ₂ Sodium chloride NaCl + array c Sodium hypochlorite array NaClO + H ₂ O array l Calcium hydroxide array Ca ( OH )₂ + Cl ₂ Calcium oxychloride CaOCl ₂ + H ₂ O
