Cycloalkanes

Characteristics:

- are cyclic saturated hydrocarbons that contain a ring of carbon atoms joined by  single bond

General formula: CnH2n

Shape of cycloalkanes:

  • cycloprophylcyclopropane > planar structure
  • cyclobutanecyclobutane > from a planar structure but it is very close to planar structure - square
  • cyclopentanecyclopentane > from a planar structure but it is very close to planar structure - pentagon
  • cyclohexanecyclohexane > forms two boundary conformations (conformation isomerism):
    • boat structure
