Isomers

Definition

Isomers are molecules with the same molecular formula but different structural arrangements. They can have different physical and chemical properties despite having the same number of each type of atom.

5 Must Know Facts For Your Next Test

1. Isomers are classified into two main types: structural isomers and stereoisomers.
2. Structural isomers have different connectivity of atoms within the molecule.
3. Stereoisomers have the same connectivity but differ in spatial arrangement.
4. Geometric isomers are a type of stereoisomer that differ in spatial arrangement around a double bond or ring structure.
5. Enantiomers are another type of stereoisomer which are non-superimposable mirror images of each other.
