如把两个成键原子核间联线叫键轴,把原子轨道沿键轴方向“头碰头”的方式重叠成键,称为σ键.把原子轨道沿键轴方向“肩并肩”的方式重叠,称为π键.三键分子一个σ键,两个π键 分析总结。 如把两个成键原子核间联线叫键轴把原子轨道沿键轴方向头碰头的方式重叠成键称为键结果...
is σ-bond (sigma-bond) and what is π-bond (pi-bond)? 答: ethene为例子.C与其它四个H所形成的single bond叫σ-bond (sigma-bond)而C与C所形成的bond是一个double bond.而double bond中就包含有一个(sigma-bond) and一个 π-bond (pi-bond)了.你可以这样记 凡是double及triple bond...

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...
chemical bonds are classified into various types such as an ionic bond, covalent bond, polar bond, and hydrogen bond. Here we will discuss the details of sigma bonds and pi bonds, which are considered as the covalent bonds. This article will help to get

Sigma and Pi bonds « on: February 03, 2013, 12:22:20 AM » Hello,I am looking at the sigma and pi bonds and trying to understand them. I know that the bond is the overlap of the orbitals, in the case of sigma bonds two s-orbitals and the pi bonds is the p-orbitals.When...
The dative sigma-bond distance is 165.5/164.0(13) pm, the two other bond distances in the ring are N-B=150.6/ 148.9(9) pm corresponding to a covalent sigma-bond and N-N = 145.1/145.4(3) pm. The terminal B-N distance 139.6/138.9(9) pm is consistent with a covalent pi-bond ...
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...
