C) show very slight magnetic character when placed in a magnetic field. A coordinate compound that is optically active has optical isomers and a coordinate compound that is not optically active does not have optical isomers. Thus, only [Co(NH3)3Cl3] complex does not show optical isomerism. The nomenclature of the complexes is patterned after a system suggested by Alfred Werner, a Swiss chemist and Nobel laureate, whose outstanding work more than 100 years ago laid the foundation for a clearer understanding of these compounds. You may need to download version 2.0 now from the Chrome Web Store. If it shows Geometric isomerism, only the cis-isomer shows optical activity.
