The bridged bicyclic norbornane, formally bicyclo[2.2.1]heptane The spirocyclic compound spiro[5.5]undecane DABCO (1,4-diazabicyclo[2.2.2]octane) is often incorrectly depicted with one skewed ethylene group for the sake of clarity.
For instance, a bicyclooctane which consists of a six-member ring and a four-member ring, which share two adjacent carbon atoms which form a shared edge, is [4.2.0]-bicyclooctane. That part of the six-member ring, exclusive of the shared edge has 4 carbons. That part of the four-member ring, exclusive of the shared edge, has 2 carbons.

The conformation of cyclooctane has been studied extensively using computational methods. Hendrickson noted that "cyclooctane is unquestionably the conformationally most complex cycloalkane owing to the existence of many conformers of comparable energy".
DABCO (1,4-diazabicyclo[2.2.2]octane), also known as triethylenediamine or TEDA, is a bicyclic organic compound with the formula N 2 (C 2 H 4) 3.This colorless solid is a highly nucleophilic tertiary amine base, which is used as a catalyst and reagent in polymerization and organic synthesis.
Bicycloheptane and bicyclooctane (seen left) are pounds in which the change in acidity with substitution was attributed to the field effect. [4] The C-X dipole is oriented away from the carboxylic acid group, and can draw electron density away because the molecule center is empty, with a low dielectric constant , so the electric field is able ...
Each non-bridgehead carbon atom is attached to two hydrogen atoms making bicycloundecane a saturated compound. It is a bicycloalkane. Other related bicycloalkanes are bicyclooctane and bicyclononane. Bicycloundecane is anisotropically conductive. It is one of several bridged hydrocarbon residues that are formed during the thermohardening of ...
