The first step of the addition of a hydrogen halide to an alkene is the addition of H+ to an sp² carbon to form a carbocation. Predict t carbocation formed in the following reaction and draw the mechanism of its formation. Edit the reaction by drawing all steps in the appropriate boxes and connecting them with reaction arrows. Add charges where needed. Electron-flow arrows should start on an atom or a bond and should end on an atom, bond, or location where a new bond should be created. DCQQ H ©\\\\\²2²0 +²√² سهند bul H с N 0 S

Question
**Title**: Mechanism of Carbocation Formation in Hydrogen Halide Addition to Alkenes **Introduction**: The first step of the addition of a hydrogen halide to an alkene is the addition of \( H^+ \) to an \( sp^2 \) carbon to form a carbocation. This educational content explains how to predict the carbocation formed in a specific reaction and how to illustrate its mechanism. **Instructions**: Edit the reaction by drawing all necessary steps in the appropriate boxes and connecting them with reaction arrows. Ensure you add charges where needed. Electron-flow arrows should start on an atom or a bond and should end on an atom, bond, or location where a new bond should be created. **Diagram Explanation**: - **Starting Material**: - The left box contains a molecular structure with a carbon-carbon double bond: \( H_2C=CH-Br \). - The alkene is highlighted with a green bond, indicating the site of reactivity. - **Mechanism Step**: - A curved arrow originates from the double bond and points towards the \( H^+ \) to illustrate the nucleophilic attack of the \( \pi \)-bond on the proton. - **Product**: - The right box shows the resulting structure post-reaction. - The structure is \( H_3C-CH_2^+ \), indicating the formation of a carbocation at the second carbon atom (sp^2 hybridized carbon). **Conclusion**: Understanding this mechanism helps in predicting the formation of carbocations, which are intermediates in many organic reactions involving alkenes. Use this information to practice predicting and drawing reaction mechanisms for similar reactions.
