i. Fill in the missing starting materials, products, or reagents as necessary. ii. Label each transformation as SN1, SN2, or acid/base. iii. Indicate if the product is racemic or a single enantiomer

a) if maltose is made up of two a-D-glucose units connected together by an a(1->4) linkage, how can it give a positive test as a reducing sugar in a pH=7 solutions such as Fehlings'? b) if a person produces and excudes a polyunsaturated oil from their skin, how does it ultimately make clothes smell bad, and how does baking soda remove the odor? (DETAILS!!! pH neutralizing is not enough!!) c) opioids are compounds derived from opium, which comes from the opium poppy. Although in reality, all poppies produce opioids, the drug "morphine", codeine as well as other opioid pain killers are typically derived from opium. A quick way to find or identify these compounds is to look for a six-membered ring containing a nitrogen. Often, if you see a six-membered ring with a nitrogen, you have some sort of an opioid or a modified synthetic painkiller. With that said morphine and codeine are typically not injected or given orally inpure form. Instead their salts are used, such as morphine sulfate…
