How to distinguish between cis and trans isomer of 1,2- dichloroethylene using plane of symmetry?
Cis and trans isomers often have different physical properties. Differences between isomers, in general, arise from the differences in the shape of the molecule or the overall dipole moment. ... The differences between cis and trans isomers can be larger if polar bonds are present, as in the 1,2-dichloroethenes.
How are trans isomers more symmetrical?
