Naming Aliphatic Chains (iupac School) — Suffix vs Prefix
Alcohols and carbonyls often take the suffix. Halogens usually prefixes. If two functions, the book gives the priority (acid beats alcohol school). 2-methylpropane not 1,1-dimethylethane — pick longest chain rule. This page separates the idea from the wider topic “NAMING ALIPHATIC CHAINS (IUPAC SCHOOL)” so it can be revised and assessed on its own.

Naming Aliphatic Chains (iupac School) — Suffix vs Prefix
What is it?
Alcohols and carbonyls often take the suffix. Halogens usually prefixes. If two functions, the book gives the priority (acid beats alcohol school). 2-methylpropane not 1,1-dimethylethane — pick longest chain rule. This page separates the idea from the wider topic “NAMING ALIPHATIC CHAINS (IUPAC SCHOOL)” so it can be revised and assessed on its own.
In simple words
- Alcohols and carbonyls often take the suffix.
- propan-1-ol
- Exam link: main group wins.
Important terms
SUFFIX VS PREFIX: Alcohols and carbonyls often take the suffix.
NAMING ALIPHATIC CHAINS (IUPAC SCHOOL): Longest chain: meth eth prop but pent hex.
What you should learn
- Define suffix vs prefix using accurate chemistry terms.
- Explain why suffix vs prefix matters within naming aliphatic chains (iupac school).
- Apply the learning unit to an FBISE-style example, comparison, diagram, or calculation.
Examples
- propan-1-ol
- propanone
- 2-chloropropane
KEY IDEA
Alcohols and carbonyls often take the suffix. Halogens usually prefixes. If two functions, the book gives the priority (acid beats alcohol school). 2-methylpropane not 1,1-dimethylethane — pick longest chain rule.
EXAM APPLICATION
Worked: CH3CHClCH3 three carbons, Cl on carbon 2 name: 2-chloropropane not 1-chloropropane (wrong number).
Recommended for Class 11

WHY — Why this topic matters
NAMING ALIPHATIC CHAINS (IUPAC SCHOOL) — SUFFIX VS PREFIX 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
Alcohols and carbonyls often take the suffix. Halogens usually prefixes. If two functions, the book gives the priority (acid beats alcohol school). 2-methylpropane not 1,1-dimethylethane — pick longest chain rule. Examples: propan-1-ol; propanone; 2-chloropropane. Exam use: Worked: CH3CHClCH3 three carbons, Cl on carbon 2 name: 2-chloropropane not 1-chloropropane (wrong number).
KEY IDEA

Common exam traps
- Do not treat suffix vs prefix as the same as every other part of naming aliphatic chains (iupac school); 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.
