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 the 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. □ C MN + T [1] A H₂C -CH₂ 7 L H EXP. CONT. i ?
