Conjugated Double bonds

Conjugated double bonds in a molecule, mean that the single and double bonds alternate.  These enables the electrons to be delocalised over the whole system and so be shared by many atoms.  This means that the delocalised electrons may move around the whole system.


"Cis" and "Trans" isomers of a compound have the same connectivites( the atoms are joined in the same sequence).  However the substituents are positioned differently, in a cis isomer the substituents are on the same face/plane of the molecule whereas a trans isomer has substituents on opposite faces/planes of the molecule.
