烃燃烧问题是高中有机化学计算中的难点之一．也是解决有机物燃烧问题的基础．如何迅速而准确地解答此类试题?笔者认为应做到以下几点．一、明确气态烃完全燃烧前后体积变化的规律 (1)若燃烧后生成的水为液态
Hydrocarbon combustion is one of the difficulties in the calculation of organic chemistry in high school. It is also the basis for solving the problem of organic combustion. How to quickly and accurately answer such questions? I believe that should do the following. First, determine the law of volume change before and after complete combustion of gaseous hydrocarbons (1) If the water generated after combustion is liquid
