Pick out the paramagnetic species of the following
(a) Fe (0) = 3d64s2. CO is a strong field ligand and hence forces 4s2electrons to shift and pair up into 3d. Thus, dsp3 geometry and n = 0.
(b) Cr (0) : 3d54s1 → 3d6 (under the influence of strong ligand CO; d2sp3hybridization (n = 0)
(c) Fe (II) : 3d6; d2sp3 hybridization (CN– – strong ligand), n = 0
(d) Ni (II) : 3d8; sp3d2 complex (no availability of two vacant 3d orbitals),n = 2
