苯、环己三烯和环己烷的键能和证明共振是不必要的

Bond Energy Sums in Benzene, Cyclohexatriene and Cyclohexane Prove Resonance Unnecessary

Raji Heyrovska

摘要:

最近的苯的新结构表明,它是由三个碳原子的半径与三个碳原子的双键半径交替在石墨。这与假设的环己三烯(凯库勒结构)不同,它涉及交替的双键和单键。结果表明,苯的原子结构的键能和与凯库勒结构的键能和之差是(错误地)被认为是由于共振的能量。这里它表明,苯的现有结构也解释了氢化成环己烷的能量及其与环己三烯的差异。

英文摘要:

The recent new structure of benzene shows that it consists of three C atoms of radii as in graphite alternating with three C atoms with double bond radii. This is different from the hypothetical cyclohexatriene (Kekule structure) involving alternate double and single bonds. It was shown that the difference in the bond energy sum of the atomic structure of benzene from that of the Kekule structure is the energy (erroneously) assumed to be due to resonance. Here it is shown that the present structure of benzene also explains the energy of hydrogenation into cyclohexane and its difference from that of cyclohexatriene.
