Study Notes
Carboxylic Acids
- The functional group of a carboxylic acid is -COOH.
Nomenclature of Aliphatic Carboxylic Acids
- Aliphatic carboxylic acids are named according to IUPAC rules.
- The parent chain is the longest chain that includes the carboxyl (-COOH) group.
Naming Other Groups in Carboxylic Acids
- Other groups bonded to the parent chain are named as substituents.
Characteristics of Aliphatic Carboxylic Acids
- Aliphatic carboxylic acids are organic compounds with a carboxyl (-COOH) group.
- They are polar molecules.
Solubility of Carboxylic Acids
- Carboxylic acids with 1-4 carbons are soluble in water.
- Carboxylic acids with 5-8 carbons are less soluble in water.
Physical Properties of Carboxylic Acids
- The boiling points of carboxylic acids are comparatively high due to hydrogen bonding.
Classification of Carboxylic Acids
- Carboxylic acids are generally considered to be weak acids.
- Carboxylic acids containing one or more C=C bonds are classified as unsaturated.
- Carboxylic acids where the carbon of the carboxyl group is bonded directly to a carbon in an aromatic ring are classified as aromatic.
Reactions of Carboxylic Acids
- The oxidation of alkyl groups attached to aromatic rings results in the formation of carboxylic acids.
- Acid chlorides, acid anhydrides, esters, and amides participate in nucleophilic acyl substitution reactions.
- The reaction of an acid with an alcohol or a phenol forms an ester.
- The reaction between thionyl chloride and carboxylic acids forms an acid chloride.
Acidity of Carboxylic Acids
- Carboxylic acids turn blue litmus to red due to their acidic property.
Condensation Reactions
- The elimination of water from two molecules of carboxylic acid forms an acid anhydride.
