结构式jiégòushì用元素符号通过价键相互连接表示分子中原子的排列顺序和结合方式的式子,在一定程度上反映分子的结构和化学性质。如分子式为C?H?O的化合物有两种,用结构式表示,分别为{structural formula; formula that uses the symbols of elements connected by valence bonds to show how the atoms and bonds in a molecule are arranged, and to reflect to a certain degree the structure of a molecule and its chemical properties, e.g. C?H?O represents two kinds of compounds, whose structural formulas are respectively}:
H H | |H—C—C—OH(乙醇{ethanol}), | | H H H H | |H—C—O—C—H(甲醚{dimethylether})。 | | H H |
