Cis-trans isomerism examples
WebJun 12, 2015 · There are two types of compounds that can exist as cis-trans isomers: (a) compounds with double bonds and (b) cyclic compounds. (a) Compounds with double bonds An alkene such as but-2-ene has two different groups on each alkene carbon. The double bond prevents rotation about the C=C axis. WebMar 1, 2024 · Cis- and trans- are given as prefixes to chemical structures. Examples of Geometric Isomers Two geometric isomers exist for Pt (NH 3) 2 Cl 2, one in which the species are arranged around the Pt in the order Cl, Cl, NH 3, NH 3, and another in which the species are ordered NH 3, Cl, NH 3, Cl.

WebFor example, consider the molecule butene (C4H8). In the molecule butene the two methyl groups (CH3) can be located on same side as the double bond (cis configuration) or opposite sides (trans configuration). The cis arrangement makes the molecule bend since the two methyl groups act to “repel” each other, whereas in the trans configuration the WebExamples of Cis trans Isomerism In 1,2 dichloroethene the double bond between the carbon means the positions of functional groups either above or below the bond are important. Due to the rigid structure of compounds, the functional groups arranged in space have different configurations. The double bonds have restricted rotation.
WebSquare planar and octahedral complexes with two pairs of different ligands exhibit cis - trans isomerism An example of a square planar complex with two pairs of ligands is the anti-cancer drug cis-platin Whereas cis- platin has beneficial medical effects by binding to DNA in cancer cells, trans- platin cannot be used in cancer treatment
