alkane series
Học thuậtThân thiện
Definition
- Noun:
- A homologous series of saturated hydrocarbons: The alkane series refers to a family of organic compounds consisting solely of carbon and hydrogen atoms connected by single bonds. These compounds follow the general chemical formula CₙH₂ₙ₊₂ and are characterized by their lack of double or triple bonds (saturation) and aromatic rings.
Usage
- The term "alkane series" is used in chemistry to categorize and discuss the simplest family of hydrocarbons, which are fundamental to organic chemistry and petroleum products.
- It is often used when discussing trends in physical properties (like boiling points) or chemical reactivity within this specific series.
Examples
- Noun:
- Methane, ethane, and propane are the first three members of the alkane series.
- The alkane series is also known as the paraffin series.
Advanced Usage
- "Normal alkanes": Refers to alkanes in the series with unbranched, straight-chain structures.
- Pentane and octane are examples of normal alkanes within the alkane series.
Variants and Related Words
- Alkane (n): An individual member of the alkane series.
- Butane is an alkane commonly used as fuel.
- Paraffin (n): A common synonym for the alkane series, especially in older or industrial contexts.
- Liquid paraffin is a mixture of higher alkanes.
Synonyms
- Paraffin series: A direct synonym.
- Saturated hydrocarbons: A broader descriptive term that includes the alkane series as its primary example.
Related Phrases
- Homologous series: A broader chemical term for a series of compounds with the same functional group and general formula, differing by a CH₂ unit. The alkane series is the classic example.
- The alkane series is a homologous series.
Noun
- a series of non-aromatic saturated hydrocarbons with the general formula CnH(2n+2)
