苯是芳香烃的典型代表,在学习“苯”知识时,同学们可能对基础知识的学习很重视,而容易忽视实验内容的分析和学习,其原因有二:一是教材中介绍的实验内容少,二是对实验本身的认识不足.以下分析几道有关苯的经典性实验题,供学习参考.一、考查苯的基本性质例1将下列各种液体分别与溴水混合并振荡,不能发生化学反应,静置后混合液分成两层,溴水层几乎无色的是() Benzene is a typical representative of aromatic hydrocarbons, learning “benzene” knowledge, students may attach importance to the learning of basic knowledge, and easy to ignore the analysis and learning of experimental content for two reasons: First, the textbook describes Less experimental content, the second is the lack of understanding of the experiment itself. The following analysis of a few classic benzene test questions for reference. First, check the basic properties of benzene Example 1 The following various liquids were mixed with bromine water and shaken , Can not occur chemical reaction, the mixture was separated into two layers after standing, Bromine water layer is almost colorless ()
