Explores the carbylamine reaction and other fundamental reactions of amines, with practice questions to test comprehension.
Boiling point depends on hydrogen bonding. (CH₃)₃N (tertiary amine) lacks hydrogen bonding, unlike CH₃NH₂ and CH₃CH₂NH₂ (primary amines), and has a lower molar mass than C₆H₅NH₂.

Amines dissolve in water due to hydrogen bonding between N-H bonds or the nitrogen lone pair and water molecules, as per the PDF’s physical properties.

Ethylamine (CH₃CH₂NH₂), a primary amine, has two N-H bonds to donate and one lone pair to accept, forming three hydrogen bonds with water, as per the PDF’s solubility discussion.

CH₃NH₂ (primary) forms hydrogen bonds, while (CH₃)₃N (tertiary) does not, leading to a higher boiling point for the former, as per the PDF.

For tertiary amines, the largest alkyl group is the parent chain. Here, ethyl (CH₂CH₃) is the parent, with two methyl groups on nitrogen, named N,N-dimethylethanamine, as per the PDF.

For tertiary amines, the largest alkyl group is the parent. Here, it’s ethanamine with N-methyl and N-ethyl groups, named N-ethyl-N-methylethanamine, as per the PDF.
Ref: NCERT Class 12 Chemistry > Chapter 13: Amines > Topic: Chemical Reactions - Carbylamine Reaction and General Reactions
The largest alkyl group is propyl, with an N-methyl substituent, named N-methylpropan-1-amine, as per the PDF’s nomenclature.
Ref: NCERT Class 12 Chemistry > Chapter 13: Amines > Topic: Chemical Reactions - Carbylamine Reaction and General Reactions
The compound has a three-carbon chain with an amino group on the second carbon. In IUPAC, it’s named propan-2-amine.

For tertiary amines, the largest alkyl group is the parent. Here, ethanamine with N-methyl and N-ethyl substituents is N-ethyl-N-methylethanamine, as per the PDF.
Ref: NCERT Class 12 Chemistry > Chapter 13: Amines > Topic: Chemical Reactions - Carbylamine Reaction and General Reactions
The compound has a four-carbon chain with an amine group on the first carbon, named butan-1-amine, as per the PDF’s nomenclature.
Ref: NCERT Class 12 Chemistry > Chapter 13: Amines > Topic: Chemical Reactions - Carbylamine Reaction and General Reactions
For secondary amines, the larger alkyl group is the parent. Here, it’s ethanamine with an N-ethyl group, named N-ethylethanamine, as per the PDF.
Ref: NCERT Class 12 Chemistry > Chapter 13: Amines > Topic: Chemical Reactions - Carbylamine Reaction and General Reactions
The compound has a two-carbon chain with an amino group on the first carbon. In IUPAC nomenclature, primary amines are named as alkanamines by replacing the 'e' of the alkane with 'amine'. Thus, CH₃CH₂NH₂ is ethanamine.
