  1. Carboxylic Acids Presented by Leticia Bonita Prince Newcastle University 4th Year MChem Student

  2. Aims of Today • Increase your understanding of carboxylic acids • Increase your spatial skills and awareness using software designed by the CCDC

  3. What are Spatial Skills? • The ability to mentally manipulate 2-dimensional and 3-dimensional figures. • Important in chemistry, biology, medicine, mathematics, physics and everyday life.

  4. Carboxylic Acids • They have the general formula RCOOH (R= H, CH3, CH2CH3etc). • Good Hydrogen bond DONORS and ACCEPTORS.

  5. Nomenclature • Look at the R group and add “-oic acid” to it. • If there are two carboxylic acid functional groups, you will add –dioic acid to it.

  6. Salts • Carboxylic acids are more acid than alcohols because their conjugate base is resonance stabilised. • This anion can form a salt by bonding ionically with a metal such as sodium.

  7. Boiling Points • Carboxylic acids have higher boiling points than alcohols. • They dimerise through hydrogen bonding creating a bigger molecule which has larger van der Waals’ – more energy to overcome.

  8. Solubility • In water, the carboxylic acid will form hydrogen bonds with water instead of dimerisingwhich is why some are soluble. • HOWEVER, if there is a large alkyl chain (5 carbons +) the carboxylic won’t dissolve due the hydrophobic nature of the R group.

  9. Reactions Alcohols Esters Amides Acyl Chlorides Acid Anhydrides Carboxylate Salts

  10. Esterification
