Norbornane Chemical Properties,Usage,Production

Description

Norbornane (also known as bicyclo[2.2.1]heptane or norcamphane) is an organic compound and a saturated hydrocarbon with chemical formula C7H12. It is a crystalline compound with a melting point of 88 °C. The carbon skeleton is derived from cyclohexane ring with a methylene bridge in the 1,4- position, and is a bridged bicyclic compound. The compound is a prototype of a class of strained bicyclic hydrocarbons.

Preparation

Norbornane is obtained by adding ethylene to cyclopentadiene under heat and pressure and then hydrogenating.

Definition

ChEBI: Norbornane is a cyclic hydrocarbon consisting of cyclohexane with a methylene bridge linking positions 1 and 4. It is a bridged compound and a cyclic hydrocarbon.
