Bicycles

from Wikipedia, the free encyclopedia

Bicyclics , also known as bicyclic compounds , are a large group of compounds in organic chemistry that contain two linked rings.

Classification

A distinction is made between the following types - depending on how the rings are linked:

  • fused connections (both rings contain a common bond)
  • Spiro compounds (both rings contain a common atom)
  • bridged connections (both rings are linked by two non-adjacent atoms)

Examples of bicyclic hydrocarbons , each containing two five-membered rings:

  • Fused bicyclic compound (fused ring system)

  • Spirocyclic compound ( Spiran )

  • Bridged bicyclic compound (bridge ring system)
