On this diagram we see: the x-axis that is a reaction coordinate: a loosely defined term meaning the reaction progress in the general direction from the starting materials or reagents (SM) to the products (Pr). the energy curve describing the energy states of the components at a certain point in the reaction. Energy Diagrams: Describing Chemical Reactions Energy Diagrams: Describing Chemical Reactions. Energy changes accompany chemical reactions. Energy diagrams are quite useful in illustrating these changes on a continuous basis as the reaction proceeds. Terms such as "activation energy" (E a), "transition state" (*), and "enthalpy change" are easy to define by referring to a graph such as ... Energy Diagram For Sn2 SN2 reaction coordinate diagram. In this diagram, there are really only three parts: the reagents, the transition state, and the products. The transition state is the point in the reaction with the highest energy level, and the difference in energy between the reagents and transition state is called the activation energy (often abbreviated as Ea).

The E1 reaction is regiospecific because it follows Zaitsev's rule that states the more substituted alkene is the major product. This infers that the hydrogen on the most substituted carbon is the most probable to be deprotonated, thus allowing for the most substituted alkene to be formed. Unlike E2 reactions, the E1 reaction is not stereospecific.

8.5. Elimination reactions | Organic Chemistry 1: An open ... E1 Reactions. Unimolecular elimination (E1) is a reaction in which the removal of an HX substituent results in the formation of a double bond. It is similar to a unimolecular nucleophilic substitution reaction (SN1) in particular because the rate determining step involves heterolysis (losing the leaving group) to form a carbocation intermediate. Because the rate determining (slow) step involves only one reactant, the reaction is unimolecular with a first order rate law.
