Mechanism for the given E1 reaction including overall reactant, overall product, and an intermediate is to be drawn. Concept introduction: E1 reaction is a unimolecular elimination reaction which takes place in two steps. In the first step, the bond between the carbon atom and the leaving group breaks to generate a carbocation, which is known as the heterolysis step. In the second step, a base removes a proton, forming an alkene . A species is an overall reactant or an overall product if it appears in the overall reaction. A species is an intermediate if it is produced in a mechanism but does not appear in the overall reaction. Also, for a mechanism that contains n number of steps, there are must be n number of transition states and n-1 number of stages representing the intermediate. The transition state appears at the local maxima and intermediate at the local minima in the free energy diagram.

+ Predict the major product of the following reaction. : ☐ + ☑ ค OH H₂SO4 Click and drag to start drawing a structure.

Consider this organic reaction: ... OH CI Draw the major products of the reaction in the drawing area below. If there won't be any major products, because this reaction won't happen at a significant rate, check the box under the drawing area instead. ☐ No Reaction. Click and drag to start drawing a structure. : а

Consider the following reactants: Br Would elimination take place at a significant rate between these reactants? Note for advanced students: by significant, we mean that the rate of elimination would be greater than the rate of competing substitution reactions. yes O no If you said elimination would take place, draw the major products in the upper drawing area. If you said elimination would take place, also draw the complete mechanism for one of the major products in the lower drawing area. If there is more than one major product, you may draw the mechanism that leads to any of them. Major Products:
