区别鉴定烯炔等不饱和化合物时,常用溴的四氯化碳溶液而不是溴水,这是为什么? 将几种不同的有机化合物一一区别开来,是化学工作者常会遇到的问题,也是有机化学教学的重要内容之一。不同物质由于结构不同,必然表现出性质上的差异。正是这些性质上的差异,成了我们能够将它们区别开来的依据。物质的性质包括物理性质、化学性质和光谱性质等几个方面,不同的物质在这几方面都会或多或少地表现出一些差异,相应地,区别物质的方法可以分为物理方法、化学方法和光谱方法等。
The difference between the identification of unsaturated compounds such as alkyne, the commonly used bromine carbon tetrachloride solution rather than bromine water, which is why? Several different organic compounds one by one out of distinction, chemical workers often encounter problems, It is also an important part of organic chemistry teaching. Due to their different structures, different substances inevitably show qualitative differences. It is these differences in nature that form the basis for our distinction. The nature of matter includes physical properties, chemical properties and spectral properties of several aspects, different substances in these areas will be more or less showed some differences, correspondingly, the material can be divided into physical methods, chemical methods And spectral methods.
