Addition of HBr to a double bond with an ether (-OR) substituent occurs regiospecifically to give a product in which the -Br and -OR are bonded to the same carbon. Draw the two possible carbocation intermediates in this electrophilic addition reaction, and explain using resonance why the observed product is formed. (FIGURE CANNOT COPY)
Explain why the addition of HBr to alkenes A and C is regioselective, forming addition products Band D, respectively.
