• Alcohols are a homologous series of compounds which have a hydroxyl group (OH) at the end.
• Alcohols General formula= CnH2n+1OH
• Alcohols are used as fuels as they are highly flammable and can also be used as solvents
• solubility decreases as alcohol size increases.
• As alcohols increase in size their melting and boiling points increase due to the increasing strength of the intermolecular forces.
• As alcohols are prepared by the addition of water, alkenes can be produced from alcohols by the removal of water. The removal of water from alcohols is called a dehydration reaction.
• Carboxylic acids are a homologous series of compounds which have a carboxyl group (-COOH) at the end.
• Carboxylic acids General formula= CnH2n+1COOH
• Carboxylic acids are used in the preparation of soaps and medicines.
• Vinegar is a solution of ethanoic acid, with molecular formula CH3COOH.
• As the size of carboxylic acids increases the solubility decreases
• As carboxylic acids increase in size their melting and boiling points increase due to the increasing strength of the intermolecular forces.
