Write the IUPAC name of the following compound

Options

  1. A2,4-dioxocyclohexanoic acid
  2. B2,4-dioxocycloheptanoic acid
  3. C4-formyl-2-oxocyclohexane-1-carboxylic acid
  4. D2,4-dioxocyclohexane-1-carboxylic acid

Correct answer

C. 4-formyl-2-oxocyclohexane-1-carboxylic acid

Step-by-step solution

Since - C H O is not in the chain, so it is designated as formyl group. group is treated as prefix 'OXO'. The - C O O H group is described in the suffix as carboxylic acid. Thus, the name is derived from the name of corresponding carboxylic acid.
