E2 reactions occur most rapidly when the H-C bond and C-LG bonds involved are co-planar, most often at 180o with respect to each other. This is described as an antiperiplanar conformation. This conformation positions the σ bonds that are being broken in the correct alignment to become the π bond.
Are E2 reactions antiperiplanar?
In The E2 Reaction, The Leaving Group Is Always “Anti-Periplanar” To The Hydrogen That Is Removed On The Adjacent Carbon (i.e. the “Beta-Carbon”)
What do E2 reactions require?
E2 reactions require the use of a reasonably strong base, so solvents which can support the base in a dissociated form are best. Aprotic solvents are actually not ideal, since they can hydrogen bond with the base and ‘buffer’ it, reducing its activity.
