In organic chemistry, a bent bond, also known as a banana bond, is a type of covalent chemical bond with a geometry somewhat reminiscent of a banana.

香蕉键，英文名称为banana bond，也称之为弯曲键，是指某些有机环状化合物，特别在3元环中，由于碳的杂化类型决定键角小于杂化轨道的伸展方向，难以形成“头碰头”的正常σ键，电子云交盖不好，重叠程度小，张力大，形成了一种弯曲的共价键。

2019年8月1日 · A banana bond is not a typical chemical bond by any stretch of the imagination. It is a 3-center, 2-electron bond. The shape of this kind of bond resembles a banana, hence its name. Perhaps the simplest example of a banana bond is demonstrated between boron and hydrogen in the diborane molecule, B 2 H 6. Elemental Atomic Orbitals

2017年7月18日 · Banana Bond is an extended covalent bond found in boranes in which a hydrogen atom is shared by two boron atoms and form of three-center two-electron bond. A banana bond is also known as a bent bond. It is a type of chemical bonding where the ordinary hybridization state of two atoms making up a chemical bond are modified with increased or ...

2023年6月21日 · Since the orbitals which overlap are not pointing directly at each other, each of these bonds is referred to as a bent bond or (more frivolously) as a banana bond. In ball-and-stick models of molecules, a double bond is usually represented by two springs or by curved sticks (shown in Figure 7.7.2 7.7. 2 ) joining the two atoms together.

Banana bonds are most often seen in cyclopropyl groups. They can be viewed as hybrids between regular σ- and π-bonds. While they are often highly-localized, their increased π-character still predestines them for π-bond like reactivity patterns.

2024年2月12日 · Coulson and Moffitt’s modification, also known as the bent bond or banana bond model, is a theoretical concept proposed in organic chemistry to explain the stability of certain strained molecules, particularly cycloalkanes.

Bent bond, also known as banana bond, is a term in organic chemistry that refers to a type of covalent chemical bond with a geometry somewhat reminiscent of a banana.

2018年11月28日 · Banana bond (bent bond) 1. In strained-ring compounds the angles assumed on the basis of hybridization are often not equal to the angles obtained by joining the ...
