Alcohols can be oxidised, which means they gain oxygen. When ethanol is oxidised it forms ethanoic acid, a carboxylic acid, and water. The equation is C2H5OH + O2 → CH3COOH + H2O. You do not need to know the oxidising agent for this specification.
This happens in real life. If a bottle of wine is left open, microbes in the air oxidise the ethanol in the wine to ethanoic acid. The wine turns sour and becomes vinegar.
The same change happens to other alcohols. Each alcohol is oxidised to the carboxylic acid with the same number of carbon atoms. Methanol gives methanoic acid, propanol gives propanoic acid and butanol gives butanoic acid. The ending of the name changes from -anol to -anoic acid. This is oxidation, not burning: the carbon chain stays the same length.
