24.(18分)
有機物A、B、C,分子式均為C5H8O2,有關的轉化關系如下圖所示。A的碳鏈無支鏈,且1mol A能與4 mol銀氨溶液完全反應。請給出A、B、C、D、E、F、G、H、I的結構簡式。
已知:
23.(10分)
已知從A出發(fā)可發(fā)生下圖所示的一系列反應,其中G為高分子化合物,化合物B的分子式為C8H8O,當以鐵做催化劑進行氯化時,一元取代物只有兩種!
填空:
(1)結構簡式:A 、M ;
(2)反應類型:I 、IV ;
(3)寫出下列反應的化學方程式:
BC: ;C+DH: 。
(4)與C互為同分異構體且均屬于酯類的芳香族的化合物共有 種。
22.(12分)
氮可以形成多種離子,如等,已知N2H5+與N2H62+是由中性分子結合質子形成的,類似于NH4+,因此有類似于NH4+的性質。

(2)的電子式為 .
(3)有 個電子。
(4)寫出等電子體物質的化學式 。(一種)
(5)等電子數(shù)的微粒往往具有相似的結構,試預測的構型 。
(6)據(jù)報道,美國科學家卡爾·克里斯特于1998年11月合成了一種名為“N5”的物質,由于其具有極強的爆炸性,又稱為“鹽粒炸彈”。迄今為止,人們對它的結構尚不清楚,只知道“N5”實際上是帶正電荷的分子碎片,其結構是對稱的,5個N排成V形。如果5個N結合后都達到8電子結構,且含有2個NN鍵。則“N5”分子碎片所帶電荷是 .
