Cis trans isomers of pent-1-ene
WebThe cis and trans structures of hex-2-ene are as shown. The cis form will have higher boiling point due to more polar nature leading to stronger intermolecular dipole-dipole … WebJan 23, 2024 · The traditional system for naming the geometric isomers of an alkene, in which the same groups are arranged differently, is to name them as cis or trans. However, it is easy to find examples where the cis-trans system is not easily applied. IUPAC has a more complete system for naming alkene isomers.
