IUPAC name of the above compound is:

  1. bicyclo[3,2,1]-octan-2-oic acid
  2. bicyclo-[3,2,1]-octane-8-carboxylic acid
  3. bicyclo-[3,2,1]-octan-8-oic acid
  4. none of these

Correct answer: bicyclo[3,2,1]-octan-2-oic acid

Solution

In bicyclic nomenclature, the bridge lengths are written in descending order, giving bicyclo[3.2.1]octane as the parent framework. The carboxylic acid group is assigned the lowest possible position, which here is carbon 2, so the correct name is bicyclo[3,2,1]-octan-2-oic acid.
