Which of the following statements are true?

Options

  1. AClO ₂ in alkaline solution undergoes disproportionation.
  2. BIonisation enthalpy of molecular oxygen is very close to that of xenon.
  3. CHydrolysis of XeF ₆ may involve a redox reaction.
  4. DBoth P ₄ O ₆ and P ₄ O ₁₀ contain 12 ~ P - O bonds

Correct answer

D. Both P ₄ O ₆ and P ₄ O ₁₀ contain 12 ~ P - O bonds

Step-by-step solution

ClO ₂ is powerful oxidising agent, also strong chlorinating agent. Its bleaching power is almost 30 times stronger than Cl ₂ . In alkaline solution undergoes disproportionation. 2 ClO ₂+2 NaOH NaClO + NaClO ₃+ H ₂ O
