Cis - trans isomerism

WebNot all alkenes will exhibit cis-trans isomerism. Criteria for Cis-Trans Isomerism. Two criteria must be satisfied in order for alkenes to exhibit cis-trans isomerism: Restricted rotation about C=C double bond (due to the presence of π bond) The 2 groups bonded to any one carbon in C=C must not be identical; This will give rise to two isomers ... WebCis and trans isomers are types of geometric isomers, where the functional group is placed differently with regards to the double bond. In general, a cis isomer has molecules on one side of the double bond. A trans isomer has molecules on the other side of the double bond. Spot the differences in the the example below:
