dienes: Compounds that contain two fixed double bonds (usually assumed to be between carbon atoms). 4, record 1, English, - diene
Record number: 1, Textual support number: 1 CONT
Dienes in which the two double-bond units are linked by one single bond are termed conjugated, e.g. CH2=CH-CH-CH2 buta-1,3-diene. Dienes in which the double bonds are adjacent are called cumulative, e.g. CH3CH=CH=CH2 buta-1,2-diene. Those in which one or more of the unsaturated carbon atoms are replaced by a heteroatom may be called heterodienes. 4, record 1, English, - diene

Les diènes dans lesquels les deux unités comportant une double liaison sont liées entre elles par une liaison simple sont dits conjugués. Par exemple : CH2=CH-CH=CH2 buta-1,3-diène. Les diènes dans lesquels les doubles liaisons sont adjacentes sont dits cumulés, par exemple : CH3-CH=C=CH2 buta-1,2-diène. Les diènes dans lesquels un ou plusieurs atomes de carbone insaturés sont remplacés par un hétéroatome sont nommés hétérodiènes. 4, record 1, French, - di%C3%A8ne
