Quick explanation
Distinguish homologous series from functional groups
- This point belongs to Introduction to organic chemistry, especially Nomenclature and formulae.
- You need to be able to distinguish homologous series from functional groups.
- The key ideas to know are homologous series and functional group.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Key concepts
Why it matters
This objective helps connect Nomenclature and formulae to exam-style questions, flashcards, and revision notes for Introduction to organic chemistry.
Quick student answer
Which of the following compounds is a member of the alcohol homologous series?
Direct answer
C3H8O is an alcohol, which contains the hydroxyl (-OH) functional group.
Key terms
- Homologous Series: A series of organic compounds with the same functional group and a gradual change in physical properties, differing by a CH2 unit.
- Functional Group: A specific group of atoms in a molecule that determines the chemical properties and reactions of that compound.
Common trap
Confusing functional groups with homologous series: Remember that a functional group is a specific group of atoms responsible for the chemical behavior, while a homologous series is a group of compounds sharing the same functional group.
