This article is about chemistry. For other uses, see Bent bond (disambiguation).
One of the first bent bond theories for cyclopropane was the Coulson-Moffitt model (1947).
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. The term itself is a general representation of electron density or configuration resembling a similar "bent" structure within small ring molecules, such as cyclopropane (C3H6) or as a representation of double or triple bonds within a compound that is an alternative to the sigma and pi bond model.
