Write balanced equations for the following (i) When chloroform is oxidised by air(ii)chloroform reacts with chlorine

Two Important oxides of carbon are carbon monox ide and carbon dioxide. Why is CO called a poisonous gas?

a. A blackish brown coloured solid A when fused with alkali metal hydroxides in presence of air produces a dark green coloured compound B which on electrolytic.oxidation in alkaline medium gives a dark purple coloured compound C. Identify A, B and C and write the reactions involved. (b) what happens when an acidic solution of the green compotind 'B' is allowed to stand for sometime? Give the equations involved. What is this type of reaction called?
