27. What are the ALL possible magnetic moments of Co(Il) in tetrahedral, octahedral, and square-planar complexes? [2 pts]
I. Co(Ⅱ) is d7.
Il. In tetrahedral complexes, it is generally high spin and has 3 unpaired electrons;
Ⅲ. In octahedral complexes, it is also typically high spin and also has 3 unpaired electrons; in square planar complexes, it has 1 unpaired electron.
IV. The magnctic moments can be calculated as μ = n(h+1) = 3.9, 3.9, and 1.6 mB, respectively.
(A) I, II
(B) I, II, II
(C) I, II, II, IV
