During the lassaigne test S and N present in organic compound changed into

Answer 1

In case, N & S both are present in the organic compound, sodium thiocyanate is formed. It gives blood red colour.

Na+N+C+S⟶FuseNa+CNS−Na+N+C+S⟶FuseNa+CNS−

F3++3CNS−⟶Fe(CNS)3F3++3CNS−⟶Fe(CNS)3

                              Ferric sulphocyanide

                             (blood red colouration
