Which reaction among the following gives nascent oxygen?

Options

  1. ANa ₂ SO ₃+ Cl ₂ H ₂ O
  2. BNaOH + Cl ₂
  3. CCa ( OH )₂+ Cl ₂
  4. 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
