【简答题】
(16分)结构的研究是有机化学最重要的研究领域。某有机物X(C 12 H 13 O 6 Br)分子中含有多种官能团,其结构下图 (其中I、II为未知部分的结构)。为推测X的分子结构,进行如下图所示的转化。 已知向D的水溶液中滴入FeCl 3 溶液显紫色,D分子中只有两种化学环境不同的氢原子,M、N互为同分异构体,M中含有一个六原子环,N能使溴的四氯化碳溶液褪色,G能与NaHCO 3 溶液反应。 请回答: (1)G分子所含官能团的名称是_________。 (2)D不可以发生的反应有(选填序号)___________。/ ①加成反应;②消去反应;③氧化反应;④取代反应 (3)写出上图转化中反应①和②的化学方程式: ① B + F →M______;②G→N________。 (4)已知向X中加入FeCl 3 溶液,无明显现象,则X的结构是______;该结构的1 mol X与足量的NaOH溶液作用,最多可消耗NaOH ______ mol。 (5)有一种化工产品的中间体W与G互为同分异构体,W的分子中只含有羧基、羟基和醛基三种官能团,且同一个碳原子上不能同时两个羟基,则W的分子结构有_____种,写出任意一种的结构___________。
