一、根据有机物相对分子质量解题例1含有氨基(—NH2)的化合物通常能够与盐酸反应,生成盐酸盐。如:R—NH2+HCl→R—NH2·HCl(R代表烷基、苯基等)。现有两种化合物A和B,它们互为同分异构体。已知:①它们都是对位二取代苯。②它们的相对分子质量都是137。③A既能被NaOH溶液中和,又可以跟盐酸反应生成盐,但不能与FeCl3溶液发生显色反应;B既不能被NaOH溶液中和,也不能跟盐酸反应生成盐。④它们的组成元素只可能是C、H、O、N、Cl中的几种。请按要求填空:
First, based on the relative molecular mass of organic matter Solution Example 1 amino (-NH2) compounds can usually react with hydrochloric acid to generate hydrochloride. Such as: R-NH2 + HCl → R-NH2 · HCl (R represents an alkyl, phenyl, etc.). There are two compounds, A and B, which are isomeric to each other. Known: 1 They are all para-disubstituted benzenes. 2 Their relative molecular mass is 137. 3A can be neutralized by NaOH solution, but it can react with hydrochloric acid to form salts, but it can not react with FeCl3 solution. B can neither be neutralized by NaOH solution nor react with hydrochloric acid to form salt. 4 Their constituent elements can only be several of C, H, O, N, and Cl.
