24.(18分)
有機(jī)物A、B、C,分子式均為C5H8O2,有關(guān)的轉(zhuǎn)化關(guān)系如下圖所示。A的碳鏈無(wú)支鏈,且1mol A能與4 mol銀氨溶液完全反應(yīng)。請(qǐng)給出A、B、C、D、E、F、G、H、I的結(jié)構(gòu)簡(jiǎn)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(yīng),其中G為高分子化合物,化合物B的分子式為C8H8O,當(dāng)以鐵做催化劑進(jìn)行氯化時(shí),一元取代物只有兩種。
填空:
(1)結(jié)構(gòu)簡(jiǎn)式:A 、M ;
(2)反應(yīng)類(lèi)型:I 、IV ;
(3)寫(xiě)出下列反應(yīng)的化學(xué)方程式:
BC: ;C+DH: 。
(4)與C互為同分異構(gòu)體且均屬于酯類(lèi)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(jié)合質(zhì)子形成的,類(lèi)似于NH4+,因此有類(lèi)似于NH4+的性質(zhì)。
(1)寫(xiě)出N2H62+與堿溶液反應(yīng)的離子方程式 。
(2)的電子式為 .
(3)有 個(gè)電子。
