What is the Lewis definition of an acid or a base? In this theory an acid is defined as an electron acceptor and a base is defined as an electron donor. What is the difference between acid and Lewis acid? An acid can be any liquid with a pH less than 7, whereas a Lewis acid spec...
2.2.3Acid-base adsorption Gilbert N. Lewis, an American physical chemist, put out the Lewis acid-base hypothesis. According to the electronic theory of acids and bases, all molecules, ions, and groups of atoms that can accept electron pairs are referred to as acids, and all molecules, ions...
常见的Lewis酸：⒈正离子、金属离子：钠离子、烷基正离子、硝基正离子 ⒉受电子分子（缺电子化合物）：三氟化硼、三氯化铝、三氧化硫、二氯卡宾 ⒊分子中的极性基团：羰基、氰基 在有机化学中Lewis酸是亲电试剂 常见的Lewis碱：⒈负离子：卤离子、氢氧根离子、烷氧基离子、烯烃、芳香化合物 ⒉带有孤电...
