近年来虽有人对芳香烃结构式的书写提出异议(如把萘的结构式写成),但至今未能得到广泛承认.人们仍习惯于沿用经典的Kekule结构式,对于稠环芳烃更是如此. 在基础有机化学教学中,依据共振论的观点,写出一组Kekule极限结构式用以分子结构分析,揭示某些化学问题,确实显得极为得心应手.可在化学反应方程式的书写等方面,则只需写出一组Kekule结构式其中之一来表示该杂化体分子.那么其中之一的选用是否随
In recent years, although people have raised objections to the structural writing of aromatic hydrocarbons (such as the structural formula of naphthalene), they have not yet been widely recognized. People are still accustomed to using the classical Kekule structure, especially for condensed aromatic hydrocarbons. Chemistry teaching, based on the resonance theory point of view, write a set of Kekeule limit structure to molecular structure analysis, reveal some of the chemical problems, it really appears very handy. In the chemical reaction equation writing, etc., just write a One of Kekule’s structural formulas represents the hybrid molecule.
