2. Propose a synthesis of each of the following molecules beginning with any alkyl halide and another neutral molecule. Choose your reagents carefully to try to favor a single mechanism (for example, charged versus neutral nucleophile/base). If you would like to use a charged molecule in your synthesis you should show the formation of that molecule from the neutral species. Pay attention to stereochemistry a. b.

11. Propose a synthesis for each compound below. You must write in all necessary reactants, reagents, and solvents to receive full credit. Your starting materials must be 3 carbons or less. If you use an ionic or organometallic species, you must show how it was synthesized from a neutral, covalent species. Any species that adds carbon to your product must be synthesized from a molecule of 3 carbons or less. Only show the steps of your synthesis- do not put...
