Interpretation:
The structure of two isomeric compounds of
Concept Introduction:
Coordination compounds: The compounds having coordination covalent bonds which form when metal ions react with polar molecules or anions.
Isomerism: Isomers are compounds with same molecular formula with different arrangements of atoms.
- Structural isomers: molecules have same molecular formula but different bonding arrangements of atoms. It is classified into coordination isomer (occurs by exchanging a coordinated ligand and the counter-ions) and linkage isomers (ligand attached through different atoms to the metal).
- Stereoisomers: differ in their spatial arrangement of atoms.
Stereoisomer: The same molecular formula but different with the arrangements of atoms around the metal ion. The Ligands are arranged differently in coordination compounds.
Geometric isomers: stereoisomers that cannot be interconverted without breaking the
b)
Interpretation:
The chemical formula of the third compound has to be predicted.
