Question
Chapter 3.2, Problem 8E
Interpretation Introduction
Interpretation: Steps involved in systematic procedure for microscale recrystallization with their purposes should be determined.
Concept introduction: Recrystallization is technique that is used for purification of organic compounds. This process includes dissolution of solid in specific solvent at high temperature and then crystals are made again by process of cooling. Temperature of crystals is decreased to allow impurities to remain in solution only.

Identify the missing starting materials/ reagents/ products in the following reactions. Show the stereochemistry clearly in the structures, if any.
If there is a major product, draw the structures of the major product with stereochemistry clearly indicated where applicable. Show only the diastereomers (you do not have to draw the pairs of enantiomers).
If you believe that multiple products are formed in approximately equal amounts (hence neither is the major product), draw the structures of the products, and show the detailed mechanism of these reactions to justify the formation of the multiple products.
If you believe no product is formed, explain why briefly. (6 mark for each, except f and g, which are 10 mark each)
3. What starting material would you use to synthesize 3-hydroxypentanoic acid using a
NaBH4 reduction?
1. Give stereochemical (Fischer projection) formulas for all (but no extras) the
stereoisomers that could theoretically form during the reduction of
a. the carbonyl group of 2-methyl-3--pentanone
b. both carbonyl groups of 2,4-pentanedione (careful!)
2. Predict the products of the reduction of O=CCH2CH2CH2C=O with
a. LiAlH4
b. NaBH4
