TRANSCRIPT

  • Slide 1
  • Carboxylic Acids
  • Slide 2
  • Nomenclature of Carboxylic Acids Esters
  • Slide 3
  • Cyclic Esters Are Known as Lactones Amides
  • Slide 4
  • Carboxylic acids have relatively high boiling points because of intermolecular hydrogen bonds Amides have the highest boiling points
  • Slide 5
  • Acidity
  • Slide 6
  • Substituent Effects on Acidity pK a = 4.46pK a = 4.19pK a = 3.47pK a = 3.41pK a = 2.16
  • Slide 7
  • Purifying an Acid by extraction
  • Slide 8
  • All carboxylic acid derivatives react by the same general mechanism The tetrahedral intermediate eliminates the weakest base tetrahedral intermediate
  • Slide 9
  • Reactions of Acyl Halides
  • Slide 10
  • Reactions of Acid Anhydrides
  • Slide 11
  • Reactions of Esters a hydrolysis reaction a transesterification
  • Slide 12
  • Fats and Oils Are Triesters of Glycerol
  • Slide 13
  • Slide 14
  • Slide 15
  • Nucleophilic Acyl Substitution of Carboxylic Acids Hydrolysis of Amides
  • Slide 16
  • The acyl halide can be used to prepare other carboxylic acid derivatives
  • Slide 17
  • Urea and Urethanes Urea is the diamide of carbonic acid. Urethanes are esters of a monoamide of carbonic acid.
