प्रश्न
Which of the following options are correct for \[\ce{[Fe(CN)6]^{3-}}\] complex?
(i) d2sp3 hybridisation
(ii) sp3d2 hybridisation
(iii) paramagnetic
(iv) diamagnetic

उत्तर
(i) d2sp3 hybridisation
(iii) paramagnetic
Explanation:
Electronic configuration Fe(26) = 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d6
CN− has a strong field ligand and electron pairing.
So, the number of the unpaired electron is 1 and paramagnetic.
