Sodium fusion extract of an organic compound gives a blood red colouration with few drops of FeCl 3 solution. This indicates the presence of

Options

  1. ANitrogen in the organic compound
  2. BSulphur in the organic compound
  3. CNitrogen and sulphur in the organic compound
  4. DSulphur and chlorine in the organic compound

Correct answer

C. Nitrogen and sulphur in the organic compound

Step-by-step solution

The presence of both nitrogen and sulphur in the lassaigne's test in an organic compound shows a blood red colouration with F e C l 3 solution. This is due to the formation of NaCNS in the sodium fusion extract.
