在高中化学选修五(有机化学基础)中,我们可以更系统地学习各类有机物知识.特别是对烃的衍生物有更多的了解,而烃的衍生物在高中阶段主要是学习卤代烃、醇、酚、醛、酸、酯.通过对代表物的学习,我们了解了基本的有机物,掌握了高中阶段常见的几种官能团的化学性质.有机部分在高考中约占20分,而考试方式以选择题和一道有机大题出现.历年高考失分最多的是在大题上.教师如何教有机、学生如何去掌握,是笔者
In High School Chemistry Elective V (Organic Chemistry Foundation), we can learn more systematically all kinds of organic matter knowledge. In particular, we know more about hydrocarbon derivatives, and the hydrocarbon derivatives mainly study halogenated hydrocarbons in high school. Alcohols, phenols, aldehydes, acids, esters. Through the learning of the representatives, we learned about the basic organics and mastered the chemical properties of several functional groups common in high school. The organic part accounts for about 20 points in the college entrance examination. Way to multiple-choice questions and an organic big question appears over the years of college entrance examination scores is the largest on the big question. How teachers teach organic, how students to master, is the author
