Which of the following answers contains all of the true statements concerning the tris(ethylenediamine)cobalt(III) ion, [Co(en)3] 3+ and no false statements? I. Each bidentate ethylenediamine ligand bonds in cis positions. II. The [Co(en)3] 3+exists in the form of a pair of nonsuperimposable mirror images. III. The coordination number of the Co metal ion is 3. IV. The [Co(en)3] 3+exists as a pair of optical isomers. V. The two optical isomers each rotate a plane of polarized light by equal amounts but in opposite directions.
