Paragraph: Upon heating KClO ₃ in the presence of catalytic amount of MnO ₂ , a gas W is formed. Excess amount of W reacts with white phosphorus to give X . The reaction of X with pure HNO ₃ gives Y and Z . Question: W and X are, respectively

Options

  1. AO 3 and P 4 O 6
  2. BO 2 and P 4 O 10
  3. CO 3 and P 4 O 10
  4. DO 2 and P 4 O 6

Correct answer

B. O 2 and P 4 O 10

Step-by-step solution

W and X are respectively W = O 2 and X = P 4 O 10
