The complex is: [ CoCl 2(e n)2] Cl. Complex is octahedral, CN of CO is 6 C o3+ has 3 d6 electronic configuration is +3

Q. The coordination number, oxidation number and the number of d-electrons in the metal ion of the complex $[COC l_{2} - (e n)_{2}] Cl$ , are respectively (atomic number of $C o = 27$ )

4,3 and 6

6, 2 and 6

6, 6 and 3

4, 2 and 6

6, 3 and 6

The complex is: $[C o C l_{2} (e n)_{2}] Cl$ .
Complex is octahedral, $CN$ of $CO$ is $6$
$C o^{3 +}$ has $3 d^{6}$ electronic configuration is $+ 3$
