特别是这条“ 所有的共振结构式必须符合Lewis结构式”怎么理解比如说.1,3-丁二烯吧.有一个共振式为(H2C+)==(C-H)-CH==CH2←→(H2C-)==(C+H)-CH==CH2这里来看.最左边的碳一个成3个共价键带一个正电荷.一个成3个键带一个正电荷它们怎么可能都符合Lewis结构.他举了一个反例 说H2C==CH==CH-...
Structures corresponding to 4 with main group fragments have been studied with the MNDO method (4: ML2 = AlH2, BH2, CH2+; R = H). For comparison the pyramidal structure 12, a D2h structure 14, and the planar six-membered ring 15 were also included. 14 was found to be the most ...
