Definition
Meaning and Definition
A homologous series of unsaturated hydrocarbons containing at least one carbon-carbon double bond, with the general formula CₙH₂ₙ.
Also known as the olefin series, these compounds are fundamental to organic chemistry, industrial synthesis (e.g., plastics, alcohols), and biochemistry. The series starts with ethene (C₂H₄), propene (C₃H₆), butene (C₄H₈), etc.
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning. 'Alkene series' is standard in both. The older term 'olefin series' is equally common in both varieties, particularly in industrial contexts.
Connotations
Purely technical, with no regional connotations.
Frequency
Equally low-frequency and highly specialised in both regions.

Common Mistakes When Using “alkene series”
- Confusing 'alkene series' with 'alkane series' (single bonds).
- Using 'alkene' to refer to the series itself, rather than a member of it.
- Misspelling as 'alkine series' (which refers to alkynes).
FAQ
Frequently Asked Questions
Yes, 'olefins' is a common synonym, especially in industrial chemistry. 'Alkene series' is the more systematic IUPAC-preferred term.
Ethene (C₂H₄), also known as ethylene.
Alkenes contain at least one carbon-carbon double bond and are unsaturated, while alkanes have only single bonds and are saturated.
Its members are crucial feedstocks for making plastics (e.g., polyethylene from ethene), solvents, antifreeze, and many other industrial chemicals.
Alkene series is usually technical/scientific in register.
Alkene series: in British English it is pronounced /ˈæl.kiːn ˈsɪə.riːz/, and in American English it is pronounced /ˈæl.kiːn ˈsɪr.iːz/. Tap the audio buttons above to hear it.

Mnemonic
Alkenes have a DOUBLE bond; think of the 'K' in alkene as two lines touching, like a double bond (K ≈ ||). The 'series' means they follow a pattern: C₂H₄, C₃H₆, C₄H₈...
Conceptual Metaphor
A FAMILY or LINEAGE (series) of compounds, each a successive 'generation' with added CH₂ units.
