Steric hindrance is a consequence of steric effects. Steric hindrance is the slowing of chemical reactions due to steric bulk. It is usually manifested in intermolecular reactions, whereas discussion of steric effects often focus on intramolecular interactions. Steric hindrance is often exploited to control … 查看更多內容 Steric effects arise from the spatial arrangement of atoms. When atoms come close together there is generally a rise in the energy of the molecule. Steric effects are nonbonding interactions that influence the shape ( 查看更多內容 • Collision theory • Reaction rate accelerate as result of steric hindrance in the Thorpe–Ingold effect • Sterically induced reduction • Intramolecular force 查看更多內容 Because steric effects have profound impact on properties, the steric properties of substituents have been assessed by numerous methods.
