Coordination Compounds - Result Question 62

####69. CNis a strong field ligand. This is due to the fact that

[2004]

(a) it carries negative charge

(b) it is a pseudohalide

(c) it can accept electrons from metal species

(d) it forms high spin complexes with metal species

Show Answer

Solution:

  1. (b) CNis a strong field ligand as it is a psuedohalide ion.

Psuedohalide ions are strong coordinating ligands and hence have the tendency to form σ-bond (from the pseudo halide to the metal) and π-bond (from the metal to pseudo halide).
