FAQs on Index: Coordination Compounds - Chemistry Class 12 - NEET

1. What are coordination compounds?
Ans. Coordination compounds are molecules or ions that consist of a central metal atom or ion bonded to one or more surrounding ligands. These ligands are typically electron donor molecules or ions that form coordinate bonds with the central metal atom.
2. How are coordination compounds named?
Ans. Coordination compounds are named using a specific nomenclature system called the IUPAC (International Union of Pure and Applied Chemistry) nomenclature. In this system, the ligands are named first, followed by the name of the central metal atom or ion. It also includes prefixes to indicate the number and arrangement of ligands and suffixes to denote the oxidation state of the central metal atom.
3. What is the role of coordination compounds in biological systems?
Ans. Coordination compounds play a crucial role in various biological systems. They are involved in processes like oxygen transport (hemoglobin), electron transfer (cytochromes), and nitrogen fixation (nitrogenase). Additionally, coordination compounds are used as essential components in many enzymes and as therapeutic agents in medicine.
4. How do coordination compounds exhibit different colors?
Ans. The color of coordination compounds is often attributed to the phenomenon of ligand-to-metal charge transfer (LMCT) or d-d transitions. These transitions occur when an electron in a ligand orbital is excited to a higher energy level or when an electron in a d-orbital of the central metal atom is excited to a higher energy level. The absorbed energy corresponds to a specific wavelength of light, giving rise to the observed color.
5. What are the applications of coordination compounds in industry?
Ans. Coordination compounds find various applications in industry. They are used as catalysts in chemical reactions, such as the production of pharmaceuticals, petrochemicals, and polymers. Coordination compounds are also employed in electroplating processes, where they help in depositing a layer of metal onto a substrate. Additionally, coordination compounds are used in the production of pigments, dyes, and as stabilizers in the formulation of agricultural pesticides.
