Definition

Noun: 1. A series of linked atoms (generally in an organic molecule): In chemistry, a "chemical chain" refers to a sequence of atoms that are connected to each other by chemical bonds. This structure is a fundamental feature of many molecules, especially in organic chemistry.

Usage

The term "chemical chain" is used to describe the linear or branched backbone structure of a molecule formed by bonded atoms. It focuses on the connectivity and sequence of the atoms themselves. * The properties of a polymer are determined by the length and structure of its chemical chain. * Organic chemists study how to break or form specific bonds within a chemical chain.

Advanced Usage

• "Chain length": Refers to the number of atoms or repeating units in the main sequence of a molecule. Longer chain lengths in hydrocarbons, for example, affect physical properties like boiling point.
  • The fuel's viscosity increases with the chain length of its hydrocarbon molecules.

Variants and Related Words

• Chain (noun): A more general term for a connected series, often used interchangeably with "chemical chain" in a molecular context.
  • A carbon chain forms the skeleton of the organic compound.
• Backbone (noun): In biochemistry, this often refers to the primary chain of a polymer, such as the sugar-phosphate backbone of DNA.
  • The protein's backbone is a polypeptide chain.
• Polymer chain (noun): A specific type of chemical chain consisting of many repeating monomer units.
  • Plastics are made of long polymer chains.

Synonyms

• Atomic chain: A sequence of linked atoms.
• Molecular chain: Emphasizes that the chain is part of a molecule's structure.

Related Phrases

• Straight chain: A chemical chain where the atoms are connected in a continuous, unbranched sequence.
  • Butane can exist in both straight-chain and branched-chain forms.
• Branched chain: A chemical chain that has smaller chains of atoms attached to the main sequence.
  • Isooctane is a branched-chain hydrocarbon used in gasoline.
• Side chain: A shorter chain of atoms attached to the main chain or backbone of a larger molecule.
  • The amino acid's properties are influenced by its side chain.
