Uses and Safety Slogans — Links
Amino acids have NH2 and COOH. Proteins: amide bonds. Nylon: diamine + diacid chloride named as a school polymer. MDMA and drug synthesis explicitly out of scope — industrial dye use of diazonium named. This page separates the idea from the wider topic “USES AND SAFETY SLOGANS” so it can be revised and assessed on its own.

Uses and Safety Slogans — Links
What is it?
Amino acids have NH2 and COOH. Proteins: amide bonds. Nylon: diamine + diacid chloride named as a school polymer. MDMA and drug synthesis explicitly out of scope — industrial dye use of diazonium named. This page separates the idea from the wider topic “USES AND SAFETY SLOGANS” so it can be revised and assessed on its own.
In simple words
- Amino acids have NH2 and COOH.
- Glycine named
- Exam link: two functional groups.
Important terms
LINKS: Amino acids have NH2 and COOH.
USES AND SAFETY SLOGANS: Amines appear in amino acids (biology), in nylon, in some named dyes.
What you should learn
- Define links using accurate chemistry terms.
- Explain why links matters within uses and safety slogans.
- Apply the learning unit to an FBISE-style example, comparison, diagram, or calculation.
Examples
- Glycine named
- Nylon-6,6 named
- Not a fibre plant
KEY IDEA
Amino acids have NH2 and COOH. Proteins: amide bonds. Nylon: diamine + diacid chloride named as a school polymer. MDMA and drug synthesis explicitly out of scope — industrial dye use of diazonium named.
EXAM APPLICATION
Exam nylon link: polyamide from a diamine and a diacid (or chloride) named amide links repeat name only, not a factory
Recommended for Class 11

WHY — Why this topic matters
USES AND SAFETY SLOGANS — LINKS 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
Amino acids have NH2 and COOH. Proteins: amide bonds. Nylon: diamine + diacid chloride named as a school polymer. MDMA and drug synthesis explicitly out of scope — industrial dye use of diazonium named. Examples: Glycine named; Nylon-6,6 named; Not a fibre plant. Exam use: Exam nylon link: polyamide from a diamine and a diacid (or chloride) named amide links repeat name only, not a factory

How the ideas connect
Amino acids have NH2 and COOH. Proteins: amide bonds. Nylon: diamine + diacid chloride named as a school polymer. MDMA and drug synthesis explicitly out of scope — industrial dye use of diazonium named. Examples: Glycine named; Nylon-6,6 named; Not a fibre plant. Exam use: Exam nylon link: polyamide from a diamine and a diacid (or chloride) named amide links repeat name only, not a factory
Deeper understanding
Go beyond memorising Uses and Safety Slogans — Links. Connect the definition to reasons, relationships, exceptions, and exam wording.

Common exam traps
- Do not treat links as the same as every other part of uses and safety slogans; define this unit and use its own evidence, steps, or conditions.
- Do not memorise a label alone; connect the definition to a process, structure, condition, equation, or example.
