So a compound with 3 carbons and 1 double bond would be propene, 3 carbons and 1 triple bond: propyne.

因此，具有 3 个碳和 1 个双键的化合物将是丙烯，3 个碳和 1 个三键：丙炔。

If there’s nothing but hydrogen and carbon, your suffix just depends on whether you have any double bonds or triple bonds; you know these, propane, propene, propyne.

如果只有氢和碳，你的后缀就取决于你有双键还是三键； 你知道这些， 丙烷，丙烯，丙炔。
