General Organic Chemistry (GOC): One-Page Formula Sheet

General Organic Chemistry (GOC) — formula sheet

Formulas

• Degree of unsaturation = (2C + 2 + N − H − X)/2
• Acidity order example: HCOOH > CH₃COOH
• Phenol is more acidic than alcohol due to resonance
• Optical isomers = 2ⁿ (n chiral centres, unsymmetrical)

Key ideas

• Stability of carbocations: 3° > 2° > 1° > methyl (plus resonance)
• −I and −M groups increase acidity
• Hyperconjugation explains alkyl group stabilisation
• Nucleophiles are electron-rich; electrophiles electron-poor

Traps to avoid

• Ignoring resonance when comparing stability
• Wrong priority in IUPAC naming
• Counting optical isomers for symmetric molecules with 2ⁿ
