MCQ
Consider the coordination compound, $\mathrm{K}_2\left[\mathrm{Cu}(\mathrm{CN})_4\right]$. A coordinate covalent bond exists between:
- A$K^+$ and $CN^-$
- ✓$Cu^{2+}$ and $CN^-$
- C$K^+$and $\ce{Cu(CN)_4}$
- D$C$ and $N$ in $CN^-$
✓
Answer
Correct option: B.
$Cu^{2+}$ and $CN^-$
The coordinate covalent bond exists between the central metal and ligand. In $\mathrm{K}_2\left[\mathrm{Cu}(\mathrm{CN})_4\right]$ ex the coordinate bond exists between $Cu^{2+}$ and $CN^-$.
