Question

The hybridization and magnetic behaviour of cobalt ion in [Co(NH3)6]3+ complex respectively is

(A) sp3d2 and paramagnetic
(B) d2sp3 and paramagnetic
(C) d2sp3 and diamagnetic
(D) sp3d2 and diamagnetic

Prashant Kotian · Accepted Answer

Correct answer: C. [Co(NH3)6]3+   Co3+ = 3d64s0  t2g2, 2, 2, eg0, 0 Hybridisation = d2sp3 Magnetic moment () = 0, diamagnetic
