PASSAGE-1
p-Amino-N, N-dimethylaniline is added to a strongly acidic solution of  X. The resulting solution is treated with a few drops of aqueous solution of Y to yield blue coloration due to the formation of methylene blue. Treatment of the aqueous solution of Y with the reagent potassium hexacyanoferrate(II) leads to the formation of an intense blue precipitate. The precipitate dissolves on excess addition of the reagent. Similarly, treatment of the solution of Y with the solution of potassium hexacyanoferrate (III) leads to a brown coloration due to the formation of Z. (2009)
Q. The compound  Y is
  • a)
    MgCl2
  • b)
    FeCl2
  • c)
    FeCl3
  • d)
    ZnCl2
Correct answer is option 'C'. Can you explain this answer?
Verified Answer
PASSAGE-1p-Amino-N, N-dimethylaniline is added to a strongly acidic so...
Reaction of Y indicates that it is Fe3+ salt.
NOTE : since the product formed (methylene blue) has sulphur in its structure, it should be supplied by the compound X which is thus Na2S.
