(a) A powdered substance (A) on treatment with fusion mixturegives a green coloured compound (B). (b) The solution of (B) on acidification with hot dilute H_(2)SO_(4) gives a pink coloured compound (C). (c) The aqueous solution of (A) on treatement with excess of NaOH and bromine water gives a compound (D). (d) A solution of (D) in conc. HNO_(3) with lead dioxide at boiling temperature produces a compound (E), which has of the same colour as that of (C). (e) A solution of (A) in dilute HCI on treatment with a solution of barium chloride gave a white precipitate of compound (F), which was insoluble in conc. HNO_(3) and conc. HCI. Compound (C) and (E) are coloured due to:
