2. Provide the major product(s) for the reactions below. Clearly indicate the stereochemistry in your structures where appropriate. Where more than one stereoisomer is formed you only need to draw one of the stereoisomeric products. Other stereoisomers should be indicated by writing, "tenantiomer" or "+diastereomer", as appropriate. Check the boxes on the right to indicate whether the reaction product solution would be optically active ([]0=0) or not optically active ([]0=0). Under the checkboxes give your rationale for the selection using one of the following: achiral, racemic, meso, single enantiomer, mixture of diastereomers. a) []D=0[]D=0 b) DMF2NaN3 []D=0[]D=0 c) CH3OH []D=0[]D=0 d) This the goal of this assignment provide practice in recognizing whether a substitution reaction will proceed by an SN1 or SN2 mechanism and predict the products 1. Given the conditions described below, indicate if a substitution reaction will proceed by an SN1 or SN2 mechanism (circle your answer). a. Electrophilic carbon: tertiary; Solvent: polar protic solvent; Nucleophile: poor; Leaving group: good SN1SN2 b. Electrophilic carbon: primary; Solvent: polar aprotic solvent; Nucleophile: good; Leaving group: good SN1SN2 c. Electrophilic carbon: secondary; Solvent: polar protic solvent; Nucleophile: poor; Leaving group: good SN1SN2 d. Electrophilic carbon: secondary; Solvent: polar aprotic solvent; Nucleophile: good; Leaving group: good SN1SN2
