Complex ion: [CrCl2 (ox)2]3- Coordination number is 6 as oxalato is a didentate ligand Oxidation state of central metal ion: x-2-4=-3, x=+3

Q. The coordination number and the oxidation state of the central metal ion in the complex ion $[C r C l_{2} (o x)_{2}]^{3 -}$ are respectively,

$4$ and $3 -$

$6$ and $3 +$

$4$ and $3 +$

$6$ and $3 -$

Complex ion : $[C r C l_{2} (o x)_{2}]^{3 -}$
Coordination number is $6$ as oxalato is a didentate ligand
Oxidation state of central metal ion :
$x - 2 - 4 = - 3$ ,
$x = + 3$
