Energy diagram for the given E1 reaction including overall reactants, overall products, the transition state, and the intermediate is to be drawn. Concept introduction: The unimolecular elimination ( E1 ) reaction is a two step reaction. The energy diagram is a plot of free energy vs reaction coordinates. The overall reactants are on the left, the overall products are on the far right. Intermediates appear at the local energy minimum in between.
