Select the correct statement(s) about oxides of carbon.

  1. ACO is a neutral oxide.
  2. BThe molecule is non-polar although each bond is polar.
  3. CCO is used as a reducing agent in the extraction of iron.
  4. DCO is an acidic oxide that dissolves in water to give carbonic acid.

Answer: A, B, C

CO does not react with water, acids or bases at ordinary conditions, so it is neutral. is linear, so the bond dipoles cancel. CO reduces in the blast furnace. Carbonic acid comes from , not CO, so the last statement is false.
