Q.
The hybridization and magnetic behaviour of cobalt ion in ${[Co {({NH}_{3})}_{6}]}^{3 +}$ complex, respectively is [2023]

1 $s p^{3} d^{2}$ and paramagnetic

2 $d^{2} s p^{3}$ and paramagnetic

3 $d^{2} s p^{3}$ and diamagnetic

4 $s p^{3} d^{2}$ and diamagnetic

Ans.
(3)

${[Co {({NH}_{3})}_{6}]}^{3 +} \to {Co}^{3 +} = 3 d^{6} 4 s^{0} \Rightarrow t_{2 g}^{2, 2, 2}, e_{g}^{0, 0}$

$Hybridisation = d^{2} s p^{3}$

$Magnetic moment (μ) = 0, diamagnetic$
