Key Topics to Revise
1
Chemical Bonds and Bond Breaking
- Organic reactions involve breaking and forming of bonds - successful reactions form stronger bonds than those broken
- Two types of bond breaking: Homolytic (equal sharing) and Heterolytic (unequal sharing)
- Homolytic cleavage: A:B → A• + B• (forms free radicals)
2
Reactive Intermediates
- Carbocations (C⁺): Electron-deficient, planar sp² hybridized, highly reactive
- Carbanions (C⁻): Electron-rich, pyramidal sp³ hybridized, nucleophilic
- Free radicals (C•): One unpaired electron, planar, highly reactive
3
Electronic Effects - Inductive Effect
- Permanent displacement of σ-electrons along carbon chain due to electronegativity differences
- Decreases with distance - effective up to 3-4 carbon atoms
- Electron withdrawing groups (-I): -NO₂, -CN, -COOH, -F, -Cl, -Br, -I
4
Electronic Effects - Resonance and Mesomeric Effects
- Delocalization of π-electrons in conjugated systems
- More important than inductive effect when both operate
- +M groups: -OH, -OR, -NH₂, -NR₂, halogens (donate electrons to ring)
