Coordination Compounds Assignments/DPPs

The captivating world of Chemistry takes a fascinating turn as we delve into “Coordination Compounds” for Class 12. This chapter introduces you to a unique class of compounds where central metal atoms join forces with surrounding molecules or ions, forming complex structures. Understanding these intricate collaborations is crucial for success in both JEE and NEET, as coordination compounds play a vital role in numerous biological processes and technological applications. Here, you’ll embark on a journey to explore the fascinating world of these compounds,

Overview : Coordination Compounds for Class 12 JEE and NEET

Coordination compounds, also known as complex compounds, are distinct from simple ionic or covalent compounds. They consist of a central metal atom or ion surrounded by molecules or ions called ligands. These ligands form coordinate covalent bonds with the central atom, sharing a pair of electrons to form a complex ion.

Building Blocks of Coordination Compounds: A Cast of Central Metals and Ligands

“Coordination Compounds” delves into the key players involved:

  • Central Metal Atom/Ion: Typically a transition metal from the d-block of the periodic table, but other metals can also form coordination compounds.

  • Ligands: Molecules or ions that donate a lone pair of electrons to form a coordinate covalent bond with the central metal atom/ion. Ligands can be classified into various types based on the number of donor atoms they possess (monodentate, bidentate, etc.) and the way they bind to the central metal atom (chelating ligands).

Understanding Nomenclature: The Language of Coordination Compounds

The chapter equips you to decipher the complex names of coordination compounds using a systematic nomenclature system. This system specifies the central metal, its oxidation state, the ligands surrounding it, and their number.

Isomerism: The Art of Disguise in Coordination Compounds

Compounds with the same formula can sometimes have different structures and properties. “Coordination Compounds” explores the concept of isomerism in these complexes. Isomers can be categorized as structural isomers (different arrangements of atoms) or stereoisomers (same arrangement but different spatial orientations). Understanding these variations is crucial for predicting the properties and behavior of coordination compounds.

Bonding Theories: Unveiling the Secrets of the Central Metal-Ligand Bond

The chapter explores two main bonding theories that explain the formation of coordinate bonds in coordination compounds:

  • Crystal Field Theory (CFT): This theory focuses on the interaction between the d-orbitals of the central metal and the electrons from the ligands. It explains the observed colors of many coordination compounds and helps predict their magnetic properties.

  • Valence Bond Theory (VBT): This theory describes the formation of coordinate bonds using the concept of hybridization of d-orbitals of the central metal with the orbitals of the ligand atoms.
