Key terms

  • Isomerism: Isomerism is the phenomenon where compounds with the same molecular formula exist in different structural forms.
  • Structural Isomers: Structural isomers are compounds that differ in the connectivity of their atoms, leading to different structural formulas.

Common trap

Confusing structural isomers with stereoisomers: Remember that structural isomers differ in connectivity, while stereoisomers have the same connectivity but differ in spatial arrangement.
