Learn about steric effect (both primary and secondary) and their effects. See examples of each effect identified. Related to this Question What is steric strain in organic chemistry? What is steric effect in organic chemistry? What is steric hindrance in organic chemistry?
Predicting chemical reactivity is an important part of the study of organic chemistry as it allows insight into the nature of chemical bonds and the behaviour of molecules. A central concept that applies to most explanations for observed reactivity is concerned with the stabilization of charge and ...
What is steric hindrance in biology? The constraint on a reaction or conformational change that is due to crowding of atoms within the van der Waals radii of other atoms. What does less hindered mean in organic chemistry? 'Less hindered hydrogen' basically means thathydrogen that leads to the...

Lithium bistrimethylsilylamide is also called lithium hexamethylsilylamide (LiHMDS). Lithium bistrimethylsilylamide can be used to prepare low-coordination metal complexes because the ligand (TMS) 2N- has a large steric hindrance. Such examples are M[N(TMS)2]3 (M=Sc,Ti,V,Fe; TMS=(CH3)3SCh...
1) The effect you already mentioned, where a hoffman alkene is often favored as the result of an E2 reaction2) The slowing down of a competing Sn2 reaction, which increases the yield of E2 elimination product. The Sn2 rate is very sensitive to steric hindrance, while E2 is much less ...

Since, when discussing nucleophilicity, we’re often discussing reactions at carbon, we have to take into account that orbitals at carbon that participate in reactions are generally less accessible than protons are. An effect called “steric hindrance” comes into play. The bottom line here is tha...
