| 摘 要： | 共振能是结构化学和有机化学中的基本概念,用来衡量一种共扼分子的稳定性,其值一般可以通过量子化学计算得到。本实验通过测定苯、环己烯和环己烷这三种物质的燃烧热,利用燃烧热数据运用差值法估算苯的共振能为84.2 K J/m o l,说明苯分子共轭后稳定性增强。

| Abstract: | Resonance energy,an important conception in organic chemistry and construction chemistry,can be used to measure the stability of conjugated molecule,whose value can be caculated by quantum chemistry. By measuring the heat of combustion of benzene,cyclohexane and cyclohexene and by using the difference of values ,this article estimates the resonance energy of benzene to be 84. 2 KJ/mol,which shows that the stability of benzene molecule increases after its conjugation. |
