📌 Key Facts Summary
- Functional group: -OH (hydroxyl group)
- General formula: CₙH₂ₙ₊₁OH
- First four: Methanol (CH₃OH), Ethanol (C₂H₅OH), Propanol (C₃H₇OH), Butanol (C₄H₉OH)
- Solubility: Short alcohols dissolve in water due to hydrogen bonding
- Fermentation: Glucose + yeast → ethanol + CO₂ (renewable, slow)
- Hydration: Ethene + steam → ethanol (industrial, fast, H₃PO₄ catalyst)
- Combustion: Burns cleanly to give CO₂ + H₂O
- Oxidation: Alcohols → carboxylic acids
