There are many selective reducing agents that are also not normally covered in a lecture course. One of these is sodium triacetoxyborohydride, NaBH(OAc)3. Shown below is a structure with both aldehyde and ketone functional groups. NaBH(OAc)3 will selectively reduce one of these two functional groups. Using the infrared spectrum provided below as evidence. What is the product of this reduction reaction, A, B, or C?   A.      B.      C.      Problem viewing the image, Click Here   IR Correlation Chart (see below)  

In the Aldol synthesis shown in the equation given below, you start with 0.45 grams of the aldehyde and you isolate 0.12 grams of the Aldol product. In this reaction, 2 molecules of the aldehyde react to make one molecule of the product. To complete this question you will need to determine the molecular weights of the reactant and the product.

There are many selective oxidizing reagents that are often not covered in a lecture course. One of these is potassium permanganate, KMnO4. You do not need to know how potassium permanganate works in order to answer this question. Shown below is oxidation of an alcohol with potassium permanganate. There are two possible products, A and B. Using the infrared spectrum of the actual product provided below, decide whether the product is A or B.   Problem viewing the image, Click Here   IR Correlation Chart (see below)
