Experiment 20: Reaction of Iodoethane with Sodium Saccharin, an Ambident Nucleophile Postlab Assignment
Includes the following questions and answers: 1. Under which class of substitution reaction (SN1 or SN2) does this reaction appear to fall? Explain 2. Considering the two resonance structures of the conjugate base of saccharin, which atom (N or O) bears more of the negative charge? Explain why? 3. What will be the possible effect on your results if you used water as the reaction solvent instead of dimethylformamide (DMF)? 4. Most compounds that contain N-H bonds are basic but saccharin is acidic...
