Which of the following statements strictly concerning Ring-Chain Isomerism are correct according to — Isomerism and Stereochemistry Chemistry Question

💡 Solution & Explanation

Ring-chain isomers differ in open vs. closed-chain structure, implying different functional properties (e.g., alkene vs cycloalkane), making them a subset of functional isomers. By IUPAC convention, the "ring-chain" designation is given priority over "functional". Cyclohexane and 1-hexene are ring-chain isomers, not positional isomers. Structurally, any cyclic compound inherently contributes 1 to the DU calculation.
