Please explain with as much detail as possible

Draw both resonance structures of the most stable carbocation intermediate in the reaction shown. +HBr - You do not have to consider stereochemistry. - Do not include anionic counter-ions, e.g., I, in your answer. - Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right - Separate resonance structures using the symbol from the drop-down menu
