**Understanding Carbocation Rearrangement in Electrophilic Addition Reactions** In this educational section, we illustrate and explain the mechanism behind a specific electrophilic addition reaction that involves a carbocation rearrangement. ### Reaction Overview The initial reaction involves a double bond compound reacting with hydrogen chloride (HCl): - **Reactants:** A compound with a double bond - **Reagent:** HCl An arrow points from the HCl towards the double bond, indicating the electrophilic addition reaction. ### Mechanism Step In the subsequent step, we need to illustrate the electron reorganization using curved arrows. These arrows specify the origin and new destinations of the electrons during the reaction. Following this is an explanation of the conventions for regioselective electrophilic attacks on double bonds. #### Detailed Mechanism Description 1. **Initial Structure and Attack:** - The structure is a double-bonded hydrocarbon. - HCl is added, and the proton (H⁺) is attracted to the electron-rich double bond. 2. **Carbocation Formation:** - This addition of H⁺ results in a positively charged carbon (carbocation). 3. **Carbocation Rearrangement:** - In this step, electron-pushing arrows are used to show how a carbocation may rearrange to form a more stable structure. - Typically, the movement of electrons happens from a less stable carbocation to form a more stable one (e.g., secondary to tertiary). 4. **Final Step:** - A chloride ion (Cl⁻) then attaches to the carbocation leading to the final product. The given diagram includes an arrow-pushing instruction, which may show different electron movement steps. This involves: - **Arrow legends:** Using curved arrows to demonstrate the reorganization of electrons. - **Electron sources and destinations:** Indicating where electrons are moving from and to during the rearrangement. ### Diagram Interpretation The first image shows the structure of the initial reactant with a double bond, interacting with HCl indicated by a rightward arrow. The second diagram displays the carbocation intermediate with reorganization arrows leading up to the final step where the chloride ion attaches, forming the final product. This mechanistic insight into electrophilic addition reactions and carbocation rearrangements provides a thorough understanding essential for advanced studies in organic chemistry.
