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.

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.

2012年5月4日 · Diborane has the interesting property of having two 3-centered bonds that are each held together by only 2 electrons (see the diagram below, from Wikipedia). These are known as "banana bonds." ...

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.

2025年1月1日 · Banana bond chemistry delves into the unique characteristics of annulenes, including cyclooctatetraene (COT) and tropone, and their role in organic chemistry. It explores concepts such as aromaticity, resonance, and molecular orbitals, highlighting the Birch reduction, Diels-Alder reaction, and electrocyclic ring opening as essential chemical ...

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 atomic centers.

Known as banana bonds or bent bonds, bent bonds are covalent chemical bonds with a shape reminiscent of a banana. The term itself represents an alternative to the sigma and pi bond model, which depicts a density of electrons or configuration similar to a "bent" structure within certain rings, such as in cyclopropane (C3H6).

2020年5月24日 · 3C-2e BOND OR BANANA BOND: EXAMPLE FORMATION OF B 2 H 6: (1) Formation of 3C-2e bond in B 2 H 6 is best explain by MOT and total number of bond in B 2 H 6 is 6 (3C-2e=2 and 3C-4e=4) (2) Bridge bonds are longer than terminal bond because at bridge bonds electrons are delocalized at three centres.
