Chemistry - AMINES Question with Solution | TestHub
On reaction with and HCl which of the following compound will form yellow oily layer?
Options:
Answer:
Solution:
Question Explanation: The question asks to identify the compound that forms a yellow oily liquid when treated with .
Concept: This question is based on Reaction of amines with nitrous acid.
Solution:
When secondary (2°) amines react with nitrous acid (generated in situ from NaNO2 and HCl), they form N-nitroso secondary amines, which are yellow oily liquids.
General reaction:
2° amines when treated with NaNO2 forms yellow oily liq.of N-Nitroso sec. amine.
Primary amines form diazonium salts or alcohols (depending on structure).
Tertiary amines do not give this reaction.
Hence, the compound that forms a yellow oily liquid must be a secondary amine. Final Answer: Option (B)
