Question

For complex $\left[Co{\left(N{H}_3\right)}_3\right]C{l}_3]$, pick up the true statement.

• A. EAN of cobalt (Z$=$27) is 39
• B. Complex can exhibit facial and meridional isomerism
• C. Complex can show optical isomerism
• D. Hybrid state of cobalt is $ds{p}^3$

Answer 1

The correct option is B Complex can exhibit facial and meridional isomerism

$EAN-36$
Octahedral complex of type $M{a}_3{b}_3$ exhibits facial and meridonal isomerism.
Complex can't show optical isomerism as it is symmetric.
Hybridization- $d^{2}s{p}^3$.
