Correct answer: C. Phthalic acid

  • A. Butanoic acid
  • B. Propionic acid
  • C. Phthalic acid
  • D. Acetic acid

Explanation

Fatty acids are in fact carboxylic acids with long aliphatic chains, which can be saturated (containing only C-C single bonds) or unsaturated (containing one or more carbon-carbon double bonds). Examples of saturated fatty acids are Palmitic acid, Stearic acid, etc. whereas examples of unsaturated fatty acids include Oleic acid, Linoleic acid, etc.Phthalic acid is not a fatty acid, it is an aromatic dicarboxylic acid, with formula C6H4(COOH)2.

About Carboxylic Acids

Carboxylic acids are named and studied through the combined effects of the carbonyl and hydroxyl groups, their preparation, acidity and hydrogen bonding. Reactions include neutralisation, esterification, reduction and conversion into acid chlorides, anhydrides, esters and amides, with emphasis on how these derivatives interconvert.
