Give the structures of both of the 1,2 and 1,4 intermediates and products for the reaction of 1 equivalent of HBr with 2,3-dimethyl-1,3-cyclohexadiene
Draw the major 1,2- and 1,4-addition products obtained in the reaction shown. Assume that both are derived from the most stable carbocation intermediate. +HBr You do not have to consider stereochemistry. You do not have to explicitly draw H atoms. If the 1,2- and 1,4- addition products are the same due to symmetry, only draw one structure. Draw one structure per sketcher. Add additional sketchers using the drop-down menu in the bottom right corner. Separate multiple products using the +...

Draw a structural formula for the major organic product of the following reaction:Electrophilic addition of HBr to alkenes yields a bromoalkane. The reaction begins with an attack on the hydrogen of the electrophilic HBr by the electrons of the double bond to give a carbocation. This step follows Markovnikov's rule with the electrophilic H atom adding to the sp2 carbon containing the most hydrogens, leading to the formation of the most stable carbocation (1° < 2° < 3°). If possible, a...
