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 1 双键的化是烯，3 1 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.

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