  2. Q gives dark violet coloration with 1% aqueous FeCl3 solution
  3. S gives yellow precipitate with 2,4-dinitrophenylhydrazine
  4. S gives dark violet coloration with 1% aqueous FeCl3 solution

Solution




Q gives dark violet coloration with 1% aqueous FeCl3 solution because it has phenolic (-OH) group.
