Give 4 ways to prepare carboxylic acids.
Oxidation of primary alcohols Hydrolysis of esters Hydrolysis of amides Hydrolysis of nitriles
Give 4 examples of reactions of carboxylic acids.
React with alcohols to form esters React with metals and bases to form salts React with amines to form amides Reduction to form primary alcohols
Describe the m.pt/b.pt of carboxylic acids.
Carboxyl group is polar - hydrogen bonding between molecules means elevated melting and boiling points compared to non-polar molecules of similar mass
Describe the solubility of carboxylic acids.
Short chain acids are soluble in water - from H-bonds with water molecules The longer the carbon chain, the less soluble it is
