Definition

1. Adjective:
   • Having an open chain structure: In chemistry, this describes a compound whose atoms are connected in a straight or branched chain, not forming a closed ring.
   • Not cyclic; especially having parts arranged in spirals rather than whorls: In botany and other fields, this describes structures that are not arranged in circles or cycles, but instead in a spiral pattern.

Examples of Usage

• Chemistry:
  • Butane is an acyclic hydrocarbon.
  • The molecule has a simple acyclic structure.
• Botany/Biology:
  • The plant has acyclic flower parts.
  • The arrangement of leaves on the stem is acyclic.

Advanced Usage

• In graph theory: An acyclic graph is a graph that contains no cycles, meaning you cannot start at one node and follow a path that returns to it.
  • The data was organized in an acyclic directed graph.
• In computer science: An acyclic process or dependency is one that does not loop back on itself.
  • The compiler checks for acyclic dependencies between modules.

Variants and Related Words

• Acyclicity (noun): The state or property of being acyclic.
  • The acyclicity of the graph was verified by the algorithm.

Synonyms

• Non-cyclic: Not forming a cycle or ring.
• Open-chain: Having a chain structure that is not closed (specific to chemistry).
• Aliphatic: A related chemical term often used for acyclic or non-aromatic organic compounds.

Antonyms

• Cyclic: Forming or having a circle or ring.
• Closed-chain: Having a chain structure that forms a ring (chemistry).
• Cyclical: Occurring in cycles; regularly repeated.
