Reaction Mechanisms

Understand the step-by-step process of organic reactions

SN2 Mechanism

Backside Attack
R-X + Nu⁻ → R-Nu + X⁻
One-step, concerted mechanism
  • • Bimolecular reaction
  • • Inversion of configuration
  • • Favored by primary halides
  • • Strong nucleophiles preferred

SN1 Mechanism

Carbocation Formation
R-X → R⁺ + X⁻
R⁺ + Nu⁻ → R-Nu
  • • Unimolecular reaction
  • • Racemization occurs
  • • Favored by tertiary halides
  • • Weak nucleophiles acceptable

E2 Elimination

Anti-periplanar
R-CH₂-CH₂-X → R-CH=CH₂ + HX
Concerted elimination
  • • Bimolecular elimination
  • • Anti-periplanar geometry
  • • Strong base required
  • • Forms double bond
