Coordination complexes with octahedral or square planar geometries may show cis-trans isomerism. This compound has two hydrogen atoms on amongst its doubly bonded carbon atoms; it fails rule 2 and will not exist as cis and trans isomers. Recognize that cis-trans isomerism is impossible in a carbon-carbon triple bond, as https://1--3r13457.bloggerchest.com/30855688/detailed-notes-on-carabersat
