Bent's rule is able to characterize molecule geometry with accuracy. [11] [5] Bent's rule provides a reliable and robust framework for predicting the bond angles of molecules. Bent's rule accuracy and precision in predicting the geometry of real-world molecules continues to demonstrate its credibility.
Changes in composition of these orbitals is well described by Bent's rule. A trivalent group 14 radical (also known as a trivalent tetrel radical) is a molecule that contains a group 14 element (E = C, Si, Ge, Sn, Pb) with three bonds and a free radical, having the general formula of R 3 E•. Such compounds can be categorized into three ...
This difference can be attributed to more p character in the C−F bonding and more s character in the C−H bonding orbitals. The hybridisation of bond orbitals is determined by Bent's rule: "Atomic s character concentrates in orbitals directed toward electropositive substituents".
This is because according to Bent's rule, the C–F bond gains p-orbital character leading to high s-character in the C–H bonds, and H–C–H bond angles approaching those of sp 2 orbitals – e.g. 120° – leaving less for the F–C–H bond angle. The difference is again explained in terms of bent bonds. [3]
The s character rich O σ(out) lone pair orbital (also notated n O (σ)) is an ~sp 0.7 hybrid (~40% p character, 60% s character), while the p lone pair orbital (also notated n O (π)) consists of 100% p character. Both models are of value and represent the same total electron density, with the orbitals related by a unitary transformation.

Henry A. Bent (December 21, 1926 – January 3, 2015) [1] was a professor of physical chemistry who studied molecular orbitals to develop atomic hybridization and valence bond theories. [2] Bent's rule , which predicts the orbital hybridization of a central atom as a function of the electronegativities of the substituents attached to it, is ...
