  8. ESTERS

  9. An esteris an organic compound that is formed when an alcohol reacts with an acid. FANCYFRUITYFRAGRANTESTERS:Esters are chemicals that have distinctive (usually pleasant) aromas..

  11. ESTERIFICATION GEN. FORMULA Carboxylic acid + Alcohol → ESTER + Water H+/ heat Example O ║ O ║ H+/ heat CH3 – C – OH + H –O – CH3 CH3 – C – O – CH3 + H2O Acetic acid methanol methyl acetate methyl ethanoate

  12. NOMENCLATURE

  13. IUPACRULES • An ESTER is named as two words. • The first word is the alkyl group attached to the oxygen of the ESTER group. • The ending ic acid will be replaced with the suffix ate. • The common name which is used more often uses the common name of the carboxylic acid.
