cyclohexene同cyclohexane

cyclohexene is more reactive than cyclohexane. This is because each cyclohexene molecule has a C=C double bond which can undergo addition reaction readily, but cyclohexane molecule is saturated and does NOT have C=C double bond.
環己烯（cyclohexene）較環己烷（cyclohexane）活潑。這因為每個環己烯分子有一個容易進行加成反應的 C=C 雙鍵，但環己烷分子是飽和的，不含 C=C 雙鍵。


Cyclohexane are more combustible than cyclohexene. In hydrocarbons, hydrogen atoms undergoes combustion more readily than carbon atoms. The mole fraction of carbon atoms in cyclohexane (C6H12) is 6/18, while that in cyclohexene (C6H10) is 6/16. Hence, cyclohexane is more combustible due to its lower carbon content.
環己烷的可燃性較環己烯高。在碳氫化合物中，與碳原子比較，氫原子較易燃。在環己烷（C6H12）中的碳原子的摩爾分數是 6/18，而在環己烯（C6H10）中則是 6/16。由於環己烷的碳含量較低，故較易燃。
