Additional Mechanism Practice 16-36 Addition of HBr to 1-phenylpropene yields only (1-bromopro zene. Propose a mechanism...
Electrophilic addition of HBr to alkenes yields a bromoalkane. The reaction begins with an attack on the hydrogen of the electrophilic HBr by the n 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 prior to the...

Electrophilic addition of HBr to alkenes yields a bromoalkane. The reaction begins with an attack on the hydrogen of the elect HBr by the π electrons of the double bond to give a carbocation. This step follows Markovnikov's rule with the electrophilic H 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...
