Linked from

The 29 pages that link to Steric hindrance, each with the reason it gives.

• NucleophileRelated: Crowding around a nucleophilic atom can slow its approach to an electrophile.

• Conformational isomerismRelated: Crowded conformations can be higher in energy because their groups clash.

• Conformational analysisRelated: Crowded groups can raise the energy of particular conformations.

• Chemical reactivityRelated: Crowding can make a nominally reactive site difficult for another molecule to reach.

• RegioselectivityRelated: Crowding can make one reaction position less accessible than another.

• ConformationRelated: Crowded arrangements disfavor some conformations.

• AtropisomerismRelated: Crowding around the rotating bond often raises the barrier that produces atropisomerism.

• StereoselectivityRelated: Crowding can block one approach to a reaction center and favor another stereochemical outcome.

• Steric effectsRelated: This is the direct kinetic effect of crowding near a reaction site.

• Van der Waals radiusRelated: Radius-based contact estimates help identify where molecular groups obstruct approach.

• Williamson ether synthesisRelated: Crowding around the halide-bearing carbon makes the required backside attack difficult.

• Space-filling modelRelated: Overlapping spheres reveal crowding that can block molecular approaches.

• Eclipsed conformationRelated: Larger substituents can add steric repulsion when they eclipse.

• Staggered conformationRelated: In larger molecules, crowding can influence conformational preferences beyond ethane’s torsional effects.

• SubstituentRelated: Bulky substituents can block approach to a reactive site.

• AtropisomerRelated: Crowded substituents often obstruct rotation around the bond that defines an atropisomer.

• BiphenylRelated: The ortho hydrogens on biphenyl’s rings crowd one another and favor a twisted geometry.

• Derek BartonRelated: Barton’s conformational arguments often depended on crowding between substituents.

• Odd HasselRelated: Conformational analysis helps explain how crowded molecular arrangements affect reactions.

• CycloheptaneRelated: Some cycloheptane shapes bring ring atoms and hydrogens into unfavorable proximity.

• G. N. RamachandranRelated: Overlapping atomic volumes exclude much of the backbone-angle space in the plot.

• MesityleneRelated: Methyl groups crowd positions between them and can restrict access to the ring.

• Non-nucleophilic baseRelated: Bulky groups can obstruct approach to electrophilic atoms while leaving proton abstraction possible.

• Open-chain compoundRelated: Branches can crowd nearby atoms and alter chain conformations or reactivity.
