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).
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
- Br
- S
N
The Correct Option is A
Solution and Explanation
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.

Classification of Organic Compounds
Organic Compounds can be classified into:
Classification based on the structure:
The classification of organic compounds is based on structure such as:
- Acyclic or open chain compounds - Acyclic compounds are just opposite to cyclic compounds because their molecules don’t form any ring. It is called open-chain compounds because they have a linear structure.
- Cyclic or closed chain compounds - Cyclic compounds are also known as “Ring compounds.”
