The correct set that contains all kinds (basic, acidic, amphoteric and neutral) of oxides is:

Options

  1. ANa₂ O, K₂ O, Al₂ O₃ and As₂ O₃
  2. BAl₂ O₃, As₂ O₃, CO and NO
  3. CK₂ O, Cl₂ O₇, As₂ O₃ and NO
  4. DNa₂ O, N₂ O, Al₂ O₃ and CO

Correct answer

C. K₂ O, Cl₂ O₇, As₂ O₃ and NO

Step-by-step solution

K₂O is a metallic oxide and is basic in nature. Cl₂O₇ is a non-metallic oxide with a high oxidation state and is acidic in nature. As₂O₃ is a metalloid oxide and is amphoteric in nature. NO is a neutral oxide. Thus, the set K₂O, Cl₂O₇, As₂O₃ and NO contains all kinds of oxides. Answer: K₂ O, Cl₂ O₇, As₂ O₃ and NO
