     Fishing is my favorite sport. I often fished for hours without catching anything, and this doesn’t worry

me. Some fishermen are unlucky. Instead catching dish, they catch old boots and rubbish. I’m even less

luck. I never catch everything---even old boots after having been spent a whole morning in the river. So

I always go home with empty bag. “You should give up fishing,” my friends say, “It’s a waste of time.”

But they don’t realize one important thing. I’m not real interested in fishing. I’m only interested in sitting in

a boat and do nothing at all.

填空题

(16分)人们对苯及芳香烃的认识有一个不断深化的过程。

(1)由于苯的含碳量与乙炔相同,人们认为它是一种不饱和烃,写出分子式为C6H6

一种含两个叁键且无支链链烃的结构简式                                 

(2)已知分子式为 C6H6 的结构有多种,其中的两种为

①这两种结构的区别表现在:

定性方面(即化学性质方面):Ⅱ能      (选填a、b、c、d,多选扣分)而Ⅰ不能。

a.被酸性高锰酸钾溶液氧化       b.与溴水发生加成反应

c.与溴发生取代反应             d.与氢气发生加成反应

定量方面(即消耗反应物的量的方面):1 mol C6H6 与H2加成时:Ⅰ需         mol,而Ⅱ需         mol。

②今发现C6H还可能有另一种如右图立体结构:该结构的二氯代物有      种。

(3)萘也是一种芳香烃,它的分子式是C10H8 ,请你判断,它的结构简式可能是下列中

         (填入编号)。

(4)根据第(3)小题中你判断得到的萘结构简式,它不能解释萘的下列         事实(填

入编号)。

a.萘不能使溴水褪色                  b.萘能与H2发生加成反应

c.萘分子中所有原子在同一平面上      d.一溴代萘(C10H7Br)只有两种

(5)现代化学认为萘分子碳碳之间的键是
