ion in $[Co(NH_3)_6]^{3+}$ complex, respectively is

(1) $sp^{3} d^{2}$ and diamagnetic

(2) $d^{2} sp^{3}$ and paramagnetic

(3) $d^{2} sp^{3}$ and diamagnetic

(4) $sp^{3} d^{2}$ and paramagnetic

Show Answer

Answer: (3)

Solution:

Formula: Valence bond theory , magnetic moment,magnetic-moment–sqrtnn2-bohr-magneton

$[Co(NH_3)_6]^{+3}-d^{2} sp^{3}$, diamagnetic
