Appearance of blood red colour on treatment of the sodium fusion extract of an organic compound with FeSO4 in presence of concentrated H2SO4 indicates the presence of element(s).
N & S
N
The appearance of a blood red color upon this reaction indicates the presence of both nitrogen and sulphur in the compound, as they combine to form thiocyanate ions (SCN−), which react with Fe3+ to produce Fe(SCN)3 with the characteristic blood red color.
So, the correct answer is : N & S.
