Study Notes
Structural Isomers vs. Stereoisomers
- Structural isomers have the same molecular formula but differ in their connectivity of atoms. This means the atoms are bonded together in different ways.
- Stereoisomers have the same molecular formula and connectivity of atoms but differ in the arrangement of atoms in space.
Geometrical Isomerism
- Geometrical isomerism is a type of stereoisomerism where the atoms are arranged differently around a double bond or a ring structure.
- This results in cis and trans isomers, which are distinguished by the position of substituents relative to each other.
Enantiomers
- Enantiomers are a special type of stereoisomer that are mirror images of each other but cannot be superimposed. This means they are non-superimposable mirror images.
- A key characteristic of enantiomers is their ability to rotate plane-polarized light in opposite directions. One enantiomer will rotate the light clockwise (dextrorotatory), while the other will rotate it counterclockwise (levorotatory).
Isomers
- Isomers are molecules with the same molecular formula but different structures. They share the same number and types of atoms but differ in how these atoms are arranged.
Stereoisomerism
- Stereoisomerism is primarily concerned with the arrangement of atoms in space. It focuses on the spatial relationship between atoms, considering the three-dimensional structure of molecules.
