• Resumen

  • Pooling the results obtained from the reaction between bromine and the cis and trans isomers of 1,2-diphenylethylenes allows students to discover the mechanism of anti addition which is common to most situations. Expansion of this experiment to include 1,1-diphenylethylene allows students the opportunity to discover the electrophilic substitution reaction. This serves as an excellent springboard for follow-up experiments on, and discussion of, electrophilic aromatic substitution.
