Verified By Collegedunia
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.”
