When determining the principal chain between an alicyclic ring and an attached open chain, the open — IUPAC and Nomenclature Chemistry Question

💡 Solution & Explanation

Priority for selecting the parent chain is PFG > Multiple bonds > Number of carbon atoms. If the open chain has the PFG, a multiple bond, or more carbon atoms (when other factors are tied), it becomes the parent chain. Option D is false because a 6-carbon ring takes priority over a 1-carbon chain.
