Study Notes
Stereochemistry
- Stereochemistry is the branch of chemistry that deals with the three-dimensional arrangement of atoms in molecules.
Isomerism
- Isomerism is the phenomenon where two or more molecules have the same molecular formula but differ in their structural arrangement.
Configurational Isomers
- Configurational isomers are molecules that have the same molecular formula and bond sequence, but differ in their three-dimensional arrangement of atoms in space.
Constitutional Isomerism
- Constitutional isomerism is based on the differences in the order in which the atoms are bonded.
- It refers to the phenomenon where molecules have the same molecular formula but differ in their bond sequence.
Stereoisomers
- Stereoisomers are molecules that have the same molecular formula and bond sequence, but differ in their three-dimensional arrangement of atoms in space.
- Stereoisomers are distinguished from one another by their differing arrangements of atoms in space, which cannot be superimposed on each other.
Constitutional Isomerism vs Stereoisomerism
- Constitutional isomerism refers to the difference in the bond sequence, whereas stereoisomerism refers to the difference in the three-dimensional arrangement of atoms in space.
