Question
Chapter 21, Problem 31RQ
Interpretation Introduction
Interpretation:
The differences between optical and geometric isomers are to be explained.
Concept Information:
Isomerism is a phenomenon exhibited by the compounds known as isomers which have the same chemical formula but different structural arrangement of the atoms in space.
Ligands are the molecules or ions that are bonded with a coordinate covalent bond to a central metal ion.
The structure of a complex is such that the metal atom is surrounded by the ligands.
