The side chain The carboxylic acid group The amino group The alpha carbon 2. Why is it important to examine the shapes of complex biological molecules and drugs? All of the choices given So scientists can explain biochemical reactions So scientists can design medications So scientists can determine how molecules fit together 3. Determine the...
a. First, circle the leaving group and label the alpha carbon as a. b. Then, label the adjacent sp3 beta carbons as B. c. Finally, draw in the H's that can get eliminated along with the leaving group in each of these compounds. The first compound has been completed for you. HH می ) و CH3 2. Now, let's perform the elimination to make the Zaitsev (most substituted) product. Draw in the H from before and the curved arrows to...
