(a) Using valence bond theory, write the hybridization and magnetic character of the complex [ Fe ( CN ) 6 ] 4 − . (Atomic no. of Fe = 26 )
(b) Write the electronic configuration ofd 6 on the basis of crystal field theory when:
(i)∆ 0 < P and
(ii)∆ 0 > P
(b) Write the electronic configuration of
(i)
(ii)
Solution:
(a) Oxidation number of Fe is +2 in [ Fe ( CN ) 6 ] 4 −
Fe 2 + − 3 d 6 CN − ions give their six pairs of electron to the empty orbitals. The orbitals utilized for hybridization is d 2 s p 3 .
