nomenclature of carboxylic acids
Nomenclature of Carboxylic Acids
  • The IUPAC system deals with carboxylic acids similar to aldehydes.
  • Carboxyl group takes priority and it’s carbon assigned the number one.
  • Suffix: for -ane ending, drop -e and add -oic acid.
  • There are two ways to identify substituent carbons in carboxylic acid: numbers or Greek letters.
carboxylic acid examples
Carboxylic acid examples
  • 2-bromopropanoic acid (or a-bromopropanoic acid)
  • 2-methyl butenoic acid
  • 2,2-dibromopropanoic acid
  • or a, a-dibromopropanoic acid or 3-oxopentanoic acid or 3-ketopentanoic acid b- ketopentanoic acid
  • methanoic acid H-COOH (formic acid)
  • ethanoic acid CH3COOH (acetic acid)
  • benzoic acid Ar-COOH
nomenclature of esters
Nomenclature of Esters
  • Alkyl(R') alkan(R)oate (a two-part name)
  • R’= Alkyl (R') group is attached to the O
  • methylethanolate
  • isopropylbenzoate
  • ethylbutanolate
nomenclature of acid halides
Nomenclature of acid halides
  • Alkanoyl halide (-oyl halide suffix)
  • or use common acyl name from acid
  • E.g. chloride of proponoic acid is named as proponoyl chloride
nomenclature of acid anhydrides
Nomenclature of Acid Anhydrides
  • Alkanoic anhydride (-oic anhydride suffix)
  • E.g. anhydride of proponoic acid is named as proponoic anhydride
nomenclature of carboxylate salts
Nomenclature of Carboxylate salts
  • Metal alkanoate (-oate suffix for anion)
  • E.g. sodium salt of proponoic acid is
  • named as sodium proponate
physical properties of carboxylic acids
Physical properties of carboxylic acids
  • Carboxyl groups exhibit very strong hydrogen bonding.
preparation of carboxylic acids
Preparation of carboxylic acids
  • Oxidation of primary alcohol to carboxylic acid.
oxidation of aldehydes
Oxidation of Aldehydes
  • Tollen’s and Benedict’s
  • Oxidation of alkyl side chain substituted on a benzene ring
hydrolysis of esters
Hydrolysis of esters.
  • Hydrolysis of acid chlorides
  • Hydrolysis of acid anhydrides
preparation of esters esterification
Preparation of esters. Esterification
  • acid + alcohol ----> ester + H2O
fatty acids and glycerides
Fatty acids and Glycerides
  • Fatty Acids
  • Glycerides
reactions of b keto acids
Reactions of b-keto acids.
  • b-keto acids are readily decarboxylated.
