有机同分异构问题由于涉及面广、规律性强,渗透融会了中学有机化学的各部分,因此历年来倍受高考命题者所青睐。同分异构体的考查主要是判断和书写,如何才能快速准确的判断和书写呢?笔者根据多年的教学经验,现总结如下:一、如何判断否是同分异构体这类题的判断依据是要抓住同分 Organic isomerism issues due to a wide range of involved, regularity, penetration of high school organic chemistry in various parts, so many years of college entrance examination proponents favored. Isomers of the main test is to judge and write, how to quickly and accurately determine and write it? The author based on years of teaching experience, are summarized as follows: First, how to determine whether the isomers such as whether the judge Basis is to seize the same points
