The compounds in Exer cis e 25 and 27 that will exhibit cis - trans isomerism are to be stated. Concept introduction: Organic compounds which have a similar chemical formula but different structures, i.e., the atoms that are in a different spatial arrangement, they are known as structural isomers. Cis and Trans isomers are also structural or geometrical isomers. The substituents are on the same side of the double bond in cis isomer while they are on the opposite side in Trans isomer.
