*** WHAT'S COVERED ***
1. Introduction to Alcohols
* Definition as a homologous series.
* The hydroxyl (-OH) functional group and comparison with alkanes.
* Naming convention (replacing 'e' with 'ol').
* Structures and chemical formulae of the first four alcohols: methanol, ethanol, propanol, and butanol.
* The general formula for alcohols: CnH2n+1OH.
2. Properties of Alcohols
* How properties change along the series.
* Common properties of the first four alcohols: flammability, solubility, and oxidation potential.
* Flammability: Complete combustion reaction (Alcohol + O2 → CO2 + H2O) and balancing equations.
* Solubility: Ability to dissolve in water to form neutral solutions.
* Oxidation: Formation of carboxylic acids (-COOH functional group) via oxidation.
3. Uses of Alcohols
* Use as fuels due to their flammability and energy release upon combustion (e.g., spirit burners).
* Use as industrial solvents, capable of dissolving substances insoluble in water (e.g., hydrocarbons, fats, oils).
