2.(1)甲苯(1分)(2)羟基(1分)14(1分)(3)有砖红色沉淀生成(1分)CHOCOONa+2Cu(OH)2+NaOH一Cu2O++3H2O(2分)HOOCNHz(4)(2分)1(2分)(5)HC-CH0H(分)CH. CI【解析】由合战路线可知A为B为cHOOCHCH OHCHO为E为、F为CIOCCH、H为、G为nd 2SH(1)A为,其名称为甲苯CH, OHCHO2C为官能团为羟基,D为O最多有14个原子共面。(3)醛基可以被新制备的氢氧化铜溶液氧化,有砖红色沉淀CHO生成发生反应的化学方程式为+2Cu(OH)2+COONNaoH -4.+CuO￥+3H2O)。HOOC(4)E为,含有碳碳双键,双键上的两个碳原子连接的均为不同的原子或原子团,所以存在顺反异构相同原子或原子团在双键异侧为反式结构,所以E的反式结构为HOOC;H的结构简式为(5)J是E的同分异构体。①J是二取代的芳香族化合物,即苯环上有两个取代基。②核磁共振氢谱上显示J的苯环上有两种化学环境的氬,则两个取代基不同,应处于对位。③J可水解,水解产物遇到FeCl溶液显紫色,说明含有酯基,且酯基水解后生成酚羟基。则符合条件的的结构简式为H:C=cH-(xcH
