Coordination complexes with octahedral or square planar geometries could also exhibit cis-trans isomerism. This compound has two hydrogen atoms on amongst its doubly bonded carbon atoms; it fails rule two and does not exist as cis and trans isomers. Observe that cis-trans isomerism is impossible at a carbon-carbon triple bond, https://ampicillinsodium09876.like-blogs.com/30825752/what-does-chf5407-mean
