Unformatted text preview: a) a tetrahedral d 6 ion. b) [Co(H 2 O) 6 ] 2+ c) [Cr(H 2 O) 6 ] 3+ d) a square planar d 7 2 e) a compound with a magnetic moment of 5.1 Bohr magnetons 8 . Determine which of the following is paramagnetic, explain your choice, and estimate its magnetic moment. a) [Fe(CN) 6 ] 4-b) [Co(H 2 O) 6 ] 3+ c) [CoF 6 ] 3-d) [RhF 6 ] 3-9 . A compound with the empirical formula Fe(H 2 O) 4 (CN) 2 has a magnetic moment corresponding to 2 2/3 unpaired electrons per iron. How is this possible? 10 . What are the possible magnetic moments of Co(II) in octahedral, tetrahedral, and square planar complexes? 11 . The most common source of mercury is cinnabar (HgS), whereas Zn and Cd, in the same group, occur as sulfide, carbonate, silicate, and oxide. Why? 12 . CsI is much less soluble in water than CsF; LiF is much less soluble than LiI. Why?...
