Without working out all the structures,which has the larger number of structural isomers,C₁₄H₃₀ or C₁₅H₃₂?

Question

Quizplus · Accepted Answer

The number of structural isomers in a compound depends on the number of different ways its atoms can be arranged while maintaining the same molecular formula. In this case, both compounds have the same molecular formula, but the difference is in the number of carbon atoms (114 vs 115) and sulfur atoms (130 vs 132). The greater the number of atoms, the greater the possibility for isomerism. Therefore, the compound with more atoms (C₁₅H₃₂) will have a larger number of structural isomers. It is impossible to determine the exact number of isomers without working out all the structures, but we can conclude that option B is the best choice based on this reasoning.
