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. 8 Addition to alkene A is regioselective because: Alkene A forms an inductively destabilized carbocation on the C closest to the O atom. Alkene A forms a resonance stabilized carbocation on the C closest to the O atom. 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. Addition to alkene C is regioselective because: Alkene C forms a carbocation that is resonance stabilized by the COOCH3 group. Alkene C forms a secondary carbocation, which is always more stable than a primary carbocation. Alkene C forms a carbocation on the C farthest from the inductively destabilizing COOCH3 group. The Br atom is less crowded on the carbon that is farther away from the COOCH3 group.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
