Les hydrocarbures insaturés [sont ceux] dans lesquels une ou plusieurs liaisons C-C sont des liaisons multiples, c'est-à-dire résultent de la mise en commun de quatre ou de six électrons. Ces composés ne sont pas saturés puisque, grâce aux électrons supplémentaires de leurs liaisons multiples, ils peuvent fixer certains éléments; en particulier, par addition d'hydrogène ils peuvent se transformer en hydrocarbures saturés. 4, record 1, French, - hydrocarbure%20insatur%C3%A9
