Question

The hybridizations involved in $\lbrack Co(C_{2}O_{4})_{3}\rbrack^{3 -}$is

• A. $sp^{3}d^{2}$
• B. $sp^{3}d^{3}$
• C. $dsp^{3}$
• D. $d^{2}sp^{3}$

Answer 1

Answer: (D)

$d^{2}sp^{3}$

Answer 2

$\lbrack Co(C_{2}O_{4})_{3}\rbrack^{3 -}$

Oxidations state of Co = +3

$Co^{3 +}(Z = 27):3d^{6}$

Since $C_{2}O_{4}^{2 -}$is a strong filed ligand pairing will take place.
