中文简介:
大多数有机反应发生在溶液中,特别是在离子的情况下,必须考虑与相邻分子的非键合相互作用。非键相互作用,包括氢键,也决定了诸如沸点等物理性质。在大多数情况下,这些相互作用可以用静电学和极化率来理解。人工或天然离子载体(离子载体)可定制为结合特定离子。从能量上讲,水在气相中的离子离解是非常昂贵的。
课程简介: Most organic reactions occur in solution, and particularly in the case of ions, one must consider non-bonded interactions with neighboring molecules. Non-bonded interactions, including hydrogen-bonding, also determine such physical properties as boiling point. For the most part these interactions may be understood in terms of electrostatics and polarizability. Artificial or natural ion carriers (ionophores) can be tailored to bind specific ions. Energetically the ionic dissociation of water in the gas phase is prohibitively expensive.
关 键 词: 有机反应; 氢键; 离子载体
