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.

Coordination number and type of hybridisation	Distribution of hybrid orbitals in space
$a. 4, sp^3$	$i. \text{trigonal bipyramidal}$
$b. 4, dsp^2$	$ii. \text{octahedral}$
$c. 5, sp^3d$	$iii. \text{tetrahedral}$
$d. 6, d^2sp^3$	$iv. \text{square planar}$
