WebElimination Reactions. Stereoselectivity of E1 Reactions. E1 reactions are stereoselective – that is when a cis or a trans alkene can be formed, the trans isomer is generally the major product: This selectivity can be explained by simply comparing the stability of alkenes. Remember, trans alkenes are more stable because of the less steric strain.
