** 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).
