IB Chemistry HL 3.2.3 Homologous series

IB Chemistry syllabusFirst assessment 2025
Recognise homologous series from formulae and structures, and state the precise features that make compounds members of the same family.
How this is tested
- state the alkene general formula CnH2n when identifying a homologous series from formulas
- distinguish compounds in the same homologous series from those with a different functional group
- define a homologous series: same functional group and formula pattern, successive members differ by CH2
