In the coordination complex, Potassium hexacyanoferrate(II), the central atom/ion acts as,
Show Hint
The central metal accepts lone pairs from ligands.
Updated On: Oct 1, 2026
- Bronsted-Lowry acid
- Lewis base
- Lewis acid
- Bronsted-Lowry base
Show Solution
The Correct Option is C
Solution and Explanation
Step 1: Roles:
In a complex the ligand donates and the metal accepts a pair of electrons to form a coordinate bond.
Step 2: Name:
The acceptor is the Lewis acid, and the donor is the Lewis base.
Step 3: Pick:
$Fe^{2+}$ accepts six pairs from six cyanides, so it is a Lewis acid.
Final Answer:
Metal ions in complexes accept electron pairs. \[ \boxed{C} \]
