Alcohols are a group of molecules which contain a COOHan OHan OOHan NH3 group, e.g. the formula C₂H₅OH represents butanolmethanolethanolpropanol. They are members of a homologous series which have similar reactions; for example:

They burn in air to produce water and carbon dioxide, known as precipitationneutralisationcomplete combustionreduction
They react with sodium to produce hydrogen gassootcarbon monoxideoxygen gas and a salt
When dehydrated, they form diolsalkenesalkanescarboxylic acids
They react with an oxidising agent to form alcoholsamino acidscarboxylic acidssalts

Some alcohols are also used as fuels, and the amount of energy each alcohol contains can be determined by measuring the volume changedensityboiling pointtemperature change of water when they are combusted. Alcohols are often produced by filtrationprecipitationaerobic respirationfermentation, which uses yeast to make ethanol from glucose.

Carboxylic acids are a group of molecules with the functional group OHNH3OOHCOOH, e.g. methanoic acid has the formula CH2COOHCH3COOHCH3CH3COOHHCOOH.

When carboxylic acids dissolve in water, they release ions because they are acidic.
