Question:
Which among the following will not liberate nitrogen on reaction with nitrous acid?
Which among the following will not liberate nitrogen on reaction with nitrous acid?
Show Hint
Tertiary amines do not undergo diazotization and hence do not liberate nitrogen when reacted with nitrous acid.
Updated On: Apr 15, 2025
- Dimethylamine
- 2-aminopropane
- Ethylamine
- Methylamine
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Dimethylamine is a tertiary amine, and tertiary amines do not react with nitrous acid (HNO\(_2\)) to liberate nitrogen gas. On the other hand, primary and secondary amines react with nitrous acid to form diazonium salts, which then decompose to release nitrogen gas. Thus, Dimethylamine (A) does not liberate nitrogen on reaction with nitrous acid.

- Give plausible explanation for the following: (a) Diazonium salts of aromatic amines are stable.
(b) Aniline does not undergo Friedel–Crafts reaction.
(c) Aniline on nitration gives a substantial amount of meta product. - Assertion (A): Acetamide (structure: \(\text{C}_6\text{H}_5\text{NHCOCH}_3\)) is less basic than aniline.
Reason (R): Acetylation of aniline results in decrease of electron density on nitrogen. - The chemical test which can be used to distinguish between ethanamine and aniline is:
- If amines are arranged in increasing order of their basic strength in gaseous phase, the correct order will be:
