1. Identify the following reaction as: addition, elimination, substitution or rearrangement o loom of OCH3 2. For the bromination step shown here: D - Y Add arrows to show the motion of the electrons. Is it an initiation, propagation, or termination step?
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 1,2-shift of either a neighboring hydride or methyl group can occur...
