WebCis isomers are molecules with the same connectivity of atoms. They feature same side groups placed on the same side of a double bond. Trans isomers feature molecules with same side groups placed on opposite sides of a double bond. Cis isomers are almost always polar. Trans isomers are not very polar. Many trans isomers are non-polar … WebExample: but-2-ene. Isomer 1 : Step 1 : split the alkene. Step 2 : assign the relative priorities. The two attached atoms are C and H, so since the atomic numbers C > H then the -CH3 group is higher priority. Step 3 : look at the relative positions of the higher priority groups : same side = Z, hence (Z)-but-2-ene. Isomer 2 :
