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

，具有 3 个碳 1 个双键的化合物将是烯，3 个碳 1 个三键：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.

如果只有碳，你的后缀就取决于你有双键还是三键； 你知道这些， 烷，烯，炔。
