compound a is a light green crystalline solid. It gives the following tests (i) It dissolves in dilute sulphuric acid. No gas is produced. (ii) A drop of KMnO_(4) is added to the above solution. The pink colour disappears. (iii) Compound A is heated strongly. Gases B and C, with pungent smell, come out. A brown residue D is left behind. (iv) The gas mixture (B and C) is passed into a dichromate solution. The solution turns green. (v) The green solution forms step (iv) gives a white precipitate E with a solution of barium nitrate. (vi) Residue D from step (iii) is heated on charcoal in a reducing flame. It gives a magnetic substance. Name the compound A, B, C, D and E.
