WebSep 1, 2024 · Compounds with 1,4- ax,eq - or 1,2- eq,ax -bonds are always cis. For example, I have put structures of α - ( 1) and β -hexoses ( 2) in the same image. Just … WebCis/trans isomers of the peptide group [ edit] Significant delocalisation of the lone pair of electrons on the nitrogen atom gives the group a partial double-bond character. The partial double bond renders the amide group planar, occurring in either the cis or trans isomers.
