Answer: Classic coordination compounds proposed by Alfred Werner (Nobel 1913).
- A Classic coordination compounds proposed by Alfred Werner (Nobel 1913)
- B A purely covalent organic compound unrelated to coordination chemistry
- C A simple ionic solid lacking any coordinate bonds
- D An organic polymer formed by repeating monomer units
Correct answer: A. Classic coordination compounds proposed by Alfred Werner (Nobel 1913)
Explanation: Alfred Werner proposed the theory of coordination compounds and octahedral geometry for complexes in the late 1800s.
The three common coordination geometries: octahedral (6 ligands), tetrahedral (4 ligands), and square planar (4 ligands in one plane).
Concept context
Study of compounds where a central metal atom is bonded to surrounding ligands. Covers nomenclature, types of isomerism, bonding theories (VBT, CFT), and applications in medicine, photography, and industry.
