Q
Q: Which of the following is a strong field ligand?
Solution: CN- (cyanide) is a strong field ligand that causes large splitting of d-orbitals in transition metal complexes.
Steps: 5
Step 1: Understand what a ligand is. A ligand is a molecule or ion that can donate a pair of electrons to a metal atom to form a complex.
Step 2: Learn about field strength of ligands. Ligands can be classified as strong field or weak field based on how much they split the d-orbitals of the metal.
Step 3: Identify strong field ligands. Strong field ligands cause a large splitting of d-orbitals, which affects the color and magnetic properties of the complex.
Step 4: Recognize examples of strong field ligands. CN- (cyanide) is a well-known strong field ligand.
Step 5: Conclude that since CN- causes large splitting of d-orbitals, it is indeed a strong field ligand.
