Answer: Ionisation isomers.
- A Ionisation isomers
- B Geometrical isomers
- C Optical isomers
- D Linkage isomers
Correct answer: A. Ionisation isomers
Explanation: These two compounds have the same formula but the Cl and SO4 have exchanged positions inside/outside the coordination sphere.
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.
