MHT CET 2026 Chemistry question

In the coordination complex, Potassium hexacyanoferrate(II), the central atom/ion acts as,

(A)Bronsted-Lowry acid
(B)Lewis base
(C)Lewis acidCorrect
(D)Bronsted-Lowry base

Answer: (C)

Solution

Potassium hexacyanoferrate(II) is , with the central metal ion and six cyanide ligands. In a coordination compound the ligands donate lone pairs of electrons to vacant orbitals of the central metal ion, forming coordinate (dative) bonds. A species that accepts an electron pair is a Lewis
