What is the absolute minimum number of carbon atoms required for an acyclic alkane, an alkene, and a — Isomerism and Stereochemistry Chemistry Question

💡 Solution & Explanation

To exhibit chain isomerism, the principal parent carbon chain or side chain size must differ. According to standard structural rules, the minimum number of carbon atoms required by an alkane, alkene, and alkyne to show chain isomerism is 4, 4, and 5, respectively.
