Vedclass · Answer

(C) In $[Co(NH_3)_6]^{3+}$,the oxidation state of cobalt is $+3$. The valence shell electronic configuration of $Co^{3+}$ $(3d^6)$ is represented as: $3d$ ($4$ unpaired electrons),$4s$ (empty),$4p$ (empty).Since $NH_3$ is a strong field ligand,it causes pairing of electrons in the $3d$ orbitals.After pairing,the configuration becomes $t_{2g}^6 e_g^0$,meaning all electrons are paired.This makes the complex diamagnetic and a low spin complex.Therefore,the statement that it is a high spin complex is incorrect.
