Alicyclic compound

In organic chemistry, an alicyclic compound contains one or more all-carbon rings which may be either saturated or unsaturated, but do not have aromatic character.

The simplest alicyclic compounds are the monocyclic cycloalkanes: cyclopropane, cyclobutane, cyclopentane, cyclohexane, cycloheptane, cyclooctane, and so on.

The mode of ring-closing in the formation of many alicyclic compounds can be predicted by Baldwin's rules.

Otto Wallach, a German chemist, received the 1910 Nobel Prize in Chemistry for his work on alicyclic compounds.

The placement of double bonds in many alicyclic compounds can be predicted with Bredt's rule.
