摘要:

国内外许多有机化学教材认为苯的两个共振极限式是凯库勒式。本文通过梳理苯环结构的研究历史和凯库勒式的结构特征,认为该说法并不妥当,并建议将苯的两个共振极限式命名为“Pauling结构式”或“Pauling苯”。

关键词: 有机化学, 苯, 共振结构, 凯库勒式, Pauling苯

Abstract:

A variety of domestic and international organic chemistry textbooks hold the standpoint that the two resonance structures of benzene are Kekulé structures. By introducing the research history of benzene structures and the structural characteristics of Kekulé's benzene, we propose that the above standpoint should be reconsidered. We also suggest that the two resonance structures should be named as "Pauling's structure" or "Pauling benzene".

Key words: Organic chemistry, Benzene, Resonance structure, Kekulé's structure, Pauling benzene
