Question

$\left[Cu\right(N{H}_3{)}_4{]}^{2+}$ and $\left[Cu\right(CN{)}_4{]}^{2-}$ are labile complexes.

• A. True
• B. False

Answer 1

The correct option is A True

Transition metal complexes which undergo rapid substitution of one ligand for another are labile.
The four-coordinated complexes of $C{u}^{2+}$ are labile so $\left[Cu\right(N{H}_3{)}_4{]}^{2+}$ and $\left[Cu\right(CN{)}_4{]}^{2-}$ are labile complexes.
