σ键（sigma bond）是最常见的一种共价键类型。在σ键中，电子云紧密重叠，形成一个完整的平面，使得两个原子之间形成了强烈的共享电子的连接。这通常发生在两个相同原子或不同原子间的双键碳原子上。一个典型的σ键在X-HX（X代表氢的同位素）键中，例如H-Cl键就是一个典型的&sigm...
It is obvious that these two bonds are very important with the many differences. Although the difference between sigma and pi bond are complementary with each other. Still, some more important points are significant as follows: It is a fact that, if there is a single bond between two atoms,...
化学里的，Σ键和π键。
A sigma bond is a type of chemical bond that is formed through the linear or co-axial overlapping of the atomic orbitals of two atoms. On the other hand, a pi bond is a covalent bond that exists between atoms where the electrons are positioned above and below the axis connecting the nuc...
怎样判断原子轨道的重叠方式 怎样判断有几个sigma键,几个派(pi bond)键?什么是“头碰头,肩并肩”,没听课,搞不懂,比如N2为什么是一个sigma键,2个派

C2Cl2是二氯乙烯：ClCH=CHCl. 其中碳碳键是sp2杂化轨道，碳氯键是sp3杂化。C2F2是二氟乙炔：FC三CF。碳碳键是sp杂化。C-F键仍然是sp3杂化。
The calculated Fe-Fe bond distance of 2.002 in Fe2(CO)6 is shorter than those of some experimentally known M-M single bonded compounds in the range of 2.904-3.228 . Here, our detailed studies on the second and third row diatomics (five, six, seven and eight valence electrons species) ...
