Amides vs Amines
What is it?
Amides RCONH2 are not strongly basic like amines (lone pair pulled toward C=O). They hydrolyse to acids (or salts) + NH3 / amine. Nylon polyamide named. Urea named as a simple amide in some books (fertiliser name, not a plant). Meaning: look for C=O next to N to call it an amide, not an amine. No urea-bomb or illicit content — fertiliser is a name only. Amide C=O-N much less basic — lone pair delocalised into carbonyl. Nitrous acid behaviour differs for 1, 2, and 3 amines — classify before predicting the product.
In simple words
- Amides RCONH2 are not strongly basic like amines (lone pair pulled toward C=O).
- 1. TELL: Amine: no C=O on that N.
- 2. HYDROLYSIS: Acid or alkali, heat.
- Exam reminder: Exam amide vs amine: amide has C=O on the nitrogen carbon much weaker base hydrolyses to an acid (or salt) and ammonia/amine
Important terms
AMIDES VS AMINES: Amides RCONH2 are not strongly basic like amines (lone pair pulled toward C=O).
1. TELL: Amine: no C=O on that N.
2. HYDROLYSIS: Acid or alkali, heat.
What you should learn
- Explain amides vs amines in simple chemical language.
- Connect 1. tell with 2. hydrolysis using equations, observations, or trends where needed.
- Answer a short Federal Board question with the correct terms and a clear reason.
Examples
- -amine vs -amide
- Litmus
- H-bond both
TELL
Amine: no C=O on that N. Amide: carbonyl. Amine: litmus blue; amide: little basic. Ethanamide vs ethanamine names. Hydrolysis amide to acid + amine under acid or base — conditions named.
HYDROLYSIS
Acid or alkali, heat. Products: carboxylic piece + nitrogen piece. Protein peptide bonds are amides (biology link). Nylon hydrolyse named as a slogan. Proteins are polyamides peptide link — biology cross-link.

WHY — Why this topic matters
AMIDES VS AMINES is an independent FBISE learning unit because students must use its definitions, conditions, equations, or trends separately in explanations and calculations.
HOW — How it works
TELL: Amine: no C=O on that N. Amide: carbonyl. Amine: litmus blue; amide: little basic. Ethanamide vs ethanamine names. Hydrolysis amide to acid + amine under acid or base — conditions named. Examples: -amine vs -amide; Litmus; H-bond both. HYDROLYSIS: Acid or alkali, heat. Products: carboxylic piece + nitrogen piece. Protein peptide bonds are amides (biology link). Nylon hydrolyse named as a slogan. Proteins are polyamides peptide link — biology cross-link. Examples: Salt + NH3 alkali path; Acid + ammonium acid path; Peptide named. Exam amide vs amine: amide has C=O on the nitrogen carbon much weaker base hydrolyses to an acid (or salt) and ammonia/amine

Amine: no C=O on that N. Amide: carbonyl. Amine: litmus blue; amide: little basic. Ethanamide vs ethanamine names. Hydrolysis amide to acid + amine under acid or base — conditions named.
Remember
- C=O or not
Examples
- -amine vs -amide
- Litmus
- H-bond both
HYDROLYSIS
Acid or alkali, heat. Products: carboxylic piece + nitrogen piece. Protein peptide bonds are amides (biology link). Nylon hydrolyse named as a slogan. Proteins are polyamides peptide link — biology cross-link.
Remember
- heat + acid/alkali
Examples
- Salt + NH3 alkali path
- Acid + ammonium acid path
- Peptide named
Remember
- amide = C=O beside N
- not a strong base
- C=O next to N
- contrast only
- C=O or not
- heat + acid/alkali
- amide = C=O beside N
- not a strong base
How the ideas connect
Exam amide vs amine: amide has C=O on the nitrogen carbon much weaker base hydrolyses to an acid (or salt) and ammonia/amine
Deeper understanding
Go beyond memorising Amides vs Amines. Connect the definition to reasons, relationships, exceptions, and exam wording.
