Question:
Given below are two statements:
Statement I: In ‘Lassaigne’s Test’, when both nitrogen and sulphur are present in an organic compound, sodium thiocyanate is formed.
Statement II: If both nitrogen and sulphur are present in an organic compound, then the excess of
sodium used in sodium fusion will decompose the sodium thiocyanate formed to give NaCN and Na2S.
In the light of the above statements, choose the most appropriate answer from the options given below:

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.”
