Unformatted text preview: ution Reactions What differentiates these solvents from each other? Page 16 of 24 C341/Fall 2011 Chapter 7: Nucleophilic Substitution Reactions SN1 Reactions and Protic Solvents Consider the nucleophiles F‐, Cl‐, Br‐, and I‐. – In a polar, protic solvent, which should be most reactive? WHY? – In a polar, aprotic solvent, which should be most reactive? WHY? – Why does the size of the halide affect its ability to hydrogen bond? Page 17 of 24 C341/Fall 2011 5. Chapter 7: Nucleophilic Substitution Reactions Synthesizing What You Want (Practicing Problems) For the following reaction, indicate which reaction mechanism (i.e. write SN1 and/or SN2 in the blank below) the following observations would support. A. the reaction rate increased when the [Nu] was increased B. the reaction rate decreased when the [RX] was decreased C. the reaction rate increased in the presence of a polar protic solvent D. the reaction showed a rearranged product E. the reaction showed more than one product F. the reaction rate decreased when the LG was changed to Cl G. the product was an ether Page 18 of 24 C341/Fall 2011 Chapter 7: Nucleophilic Substitution Reactions Circle which of the following is a stronger nucleophile and provide a valid argument for your r...
