WebLigands can be anions, cations, and neutral molecules. Ligands act as Lewis bases (donate electron pairs) and central metal atoms viewed as Lewis acid (electron pair acceptor). The nature of bonding between metal to ligand varies from covalent bond to ionic bond. Occasionally ligands can be cations (NO +, N 2 H5 +) and electron-pair acceptors. WebQuestion: (a) Place the ligands I', NCS-(S-coordinated), SCN- (N-coordinated), and H in an order of ligand field strength in the spectrochemical series and explain how you arrive at your answers.

Webspectrochemical series. As is readily apparent from the position of the ligands in the series, π-donors give weak ligand fields (i.e. small ∆O), σ-only give intermediate ligand fields and π-acceptors give strong ligand fields.

"WebAug 16, 2024 · A strong ligand or a strong field ligand is a ligand that can result in a higher crystal field splitting. This means, the binding of a strong field ligand causes a higher difference between the higher and lower energy level orbitals. Why are strong field ligands strong? Ions at the other end are known as weak-field ions. " - Strength of ligands order
