Consider the numbering rules for functionalized bicyclic and spirocyclic compounds. Which of the fol — IUPAC and Nomenclature Chemistry Question

💡 Solution & Explanation

Numbering in bicyclo compounds strictly follows the decreasing bridge length rule regardless of substituent or functional group placement (C is correct, B is false). Spiro numbering starts in the small ring and passes through the spiro carbon (A is correct), meaning the spiro carbon is never number 1 (D is false).
