近年高考化学试卷中的有机试题,情景新颖、立意深刻,设同巧妙,突出了科学紊质和恩维能力考查,而且试题年年创新,陌生度高,反映了高考化学试题改革的方向.怎样才能掌握解好有机题的金钥匙呢?一、要有扎实的有机基础知识同分异构、同系列、同系物都是重要的有机基本概念,对这些基本概念要做到:深刻理解、准确掌握、灵活运用.例1.烯烃、一氧化碳、氢气在催化剂存在下,可发生羰基合成反应生成醛.例如:
In recent years, the organic test papers in the college entrance examination chemistry papers are novel in situation, profound in concept, ingenious in design, highlighting the scientific turbulence and examination of Enwei’s ability, and the examination questions are innovative every year, and the degree of strangeness is high, reflecting the direction of the reform of the college entrance examination chemistry test questions. In order to master the golden key for solving organic problems, one must have a solid organic basic knowledge with the same heterogeneous, homologous, and homologues as all important organic basic concepts. To do these basic concepts must be understood and accurately understood. Mastery and flexible use. Example 1. Olefin, carbon monoxide, and hydrogen in the presence of a catalyst, oxo reactions can occur to produce aldehydes. For example:
