Preferred Label : dienes;
IUPAC definition : Compounds that contain two fixed double bonds (usually assumed to be between carbon
atoms). Dienes in which the two double-bond units are linked by one single bond are
termed conjugated, e.g. CH sub 2 /sub CH–CH CH sub 2 /sub buta-1,3-diene. Dienes
in which the double bonds are adjacent are called cumulative, e.g. CH sub 3 /sub –CH
C CH sub 2 /sub buta-1,2-diene. Those in which one or more of the unsaturated carbon
atoms is replaced by a heteroatom may be called heterodienes.;
