Definition

1. 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

1. a series of non-aromatic saturated hydrocarbons with the general formula CnH(2n+2)
