Saturated Bridged Ring Systems

The Hantzsch-Widman system is well suited for the naming of saturated monocyclic compounds. Bridged ring systems, however, present a special challenge, and here the replacement system is preferred. An example is provided by the framework of the bicyclic hydrocarbon norbornane. Heteroatoms may in principle be substituted for any of the carbons. To illustrate, nitrogen substitution at position 7 would give rise to the name 7-azanorbomane. 

The parent bridged hydrocarbons also have systematic lUPAC names, and the replacement system can be applied to these names. The mles for their naming can be found elsewhere. In brief, numbering begins
