Question

Be sure to answer all parts. Explain why the addition of HBr to alkenes A and C is regioselective. forming addition products B and D. respectively. Addition to alkene A is regioselective because: Alkene A forms a primary carbocation. which is always more stable than a secondary carbocation. The Br atom is less crowded on a primary carbon than on a secondary carbon. Alkene A forms a resonance stabilized carbocation on the C closest to the O atom. Alkene A forms an inductively destabilized carbocation on the C closest to the O atom. Addition to alkene C is regioselective because: Alkene C forms a secondary carbocation which is always more stable than a primary carbocation. The Br atom is less crowded on the carbon that is farther away from the COOCH3 group. Alkene C forms a carbocation that is resonance stabilized by the COOCH3 group. Alkene C forms a carbocation on the C farthest from the inductively destabilizing COOCH3 group.
