Classification & Nomenclature

• Acyclic vs cyclic (homocyclic/heterocyclic).
• IUPAC: parent chain + suffix (functional group) + prefixes (substituents).

Isomerism

• Structural: chain, position, functional group, metamerism.

Electronic Effects

• Inductive effect (sigma bonds); Resonance (pi/lone pairs); Hyperconjugation.

Reactive Intermediates

• Carbocation, carbanion, free radical.
• Stability order (carbocations): tertiary > secondary > primary.

One-Line Summary

This chapter establishes the nomenclature, structural representation, isomerism, and electronic effects (inductive, resonance, hyperconjugation) that underpin the reactivity of all organic compounds.
