Question

Attach properly annotated spectra if assigned. Include a table with your observations on the solubility in
water, acid, and base of the norleucine, caproic acid, and hexylamine.
Answer the following questions:
1. Define zwitterionic. Explain your solubility results based on this concept.
2. Starting with a racemic mixture of 2-bromohexanoic acid, one expects a racemic mixture of
norleucine. If one started with (S)-2-bromohexanoic acid, would be the final product be R or S or
racemic?
3. Explain why you are asked to perform the solubility tests at different pHs.
4. Would you expect the reaction to proceed faster or slower if a solvent less polar than
water were used? Explain.

Explanation / Answer

1. Zwitterion: In chemistry, a zwitterion (/?tsv?t?r.a?.?n/ tsvit-?r-eye-?n; from German zwitter [?tsv?t?] "hybrid" and formerly called a dipolar ion) is a neutral molecule with a positive and a negative electrical charge, though multiple positive and negative charges can be present " From Wikipedia

Since you have not mentioned the amino acid, I will take Ph of zwitter ion to be around 7
