Bent's Rule describes and explains the relationship between the orbital hybridisations of central atoms in molecules and the electro-negativities of substituents.
The rule was stated by Henry Bent as follows:
"Atomic s character concentrates in orbitals directed toward electro-positive substituents".
Example -  molecular geometry can be explained and predicted by changing the substituent group. In the molecule Me2XCl2, (X=main group elements C, Si, Ge, Sn, Pb), the bond angle Cl-X-Cl is smaller than C-X-C bond angle. With the highly electronegative halogen substituent, Cl, more p character is concentrated on central atom in X-Cl than X-C bonds.
