WebCis and trans isomers have different physical properties. Cis -platin has clinical importance in the treatment of ovarian and testicular cancers. The biological mechanism of the drug's action was long suspected to involve binding of the platinum by DNA. WebJul 25, 2024 · Isomer cis memiliki titik didih lebih tinggi dibandingkan dengan isomer trans. Alasan untuk ini adalah gaya antarmolekul kuat dalam isomer cis. Misalnya pada 1,2-dikloroethene, ketika molekul yang cis, dua atom klorin elektronegatif berada di salah satu sisi molekul. Karena itu, sisi molekul akan memiliki sedikit muatan negatif, sementara sisi ...
WebGeometric isomers are stereoisomers that differ in the arrangement of atoms around a double bond or ring structure. The two most common types of geometric isomers are cis-isomers and trans-isomers. In a cis-isomer, the functional groups or substituents are on the same side of the molecule, while in a trans- isomer, they are on opposite sides. WebAug 14, 2024 · Cis-trans (geometric) isomerism exists when there is restricted rotation in a molecule and there are two nonidentical groups on each doubly bonded carbon atom. The IUPAC naming is the same as alkene except for the addition of the cis or trans prefix.
