WebThere are no cis or trans isomers in benzene ring because there is only one additional bond to C outside the benzene ring. Because the benzene C has a (delocalized) double bond it has trigonal planar geometry and the bond is in the plane of the benzene ring. As a result there are no cis/trans possibilities on the flat planar benzene ring.
