One-Liner Questions and Answers from Amines Chapter
- What is the functional group of amines? –NH2 (amino group).
- What is the Gabriel phthalimide synthesis? A method to prepare primary amines using phthalimide and alkyl halides.
- Why are amines basic? Due to the presence of a lone pair of electrons on nitrogen, which can accept a proton.
- What is the carbylamine reaction? A reaction in which primary amines react with chloroform and alcoholic KOH to form isocyanides.
- Why is aniline less basic than aliphatic amines? Due to resonance in the benzene ring, the lone pair of electrons on nitrogen is delocalized.
- What happens when amines react with acyl chlorides? They form amides.
- How are secondary and tertiary amines identified? By their reactions with nitrous acid.
- What is the effect of alkyl groups on the basicity of amines? Alkyl groups increase the basicity by donating electrons.
Conclusion
“Amines” is an essential chapter in Class 12 Chemistry that explains the structure, properties, and reactions of nitrogen-containing compounds. The concepts from this chapter are not only crucial for exams but also for understanding the role of amines in industrial and biological processes.
