Which one of the following acids does not exhibit optical isomerism?

Options

  1. ALactic acid
  2. BTartaric acid
  3. CMaleic acid
  4. D-amino acids

Correct answer

C. Maleic acid

Step-by-step solution

Optical isomers contain an asymmetric (chiral) carbon atom (a carbon atom attached to four different atoms or groups). Therefore all except maleic acid exhibit optical isomerism.
