For the following reaction, the cyanide nucleophile could reasonably substitute at either of two positions. One mechanism produces 4-cyanoheptane and dimethylsulfide. The competing mechanism produces 4-methylthioheptane and acetonitrile (CH_3CN). In practice, only one substitution is observed. Choose the most likely mechanistic pathway for this reaction and draw both of the products. Select whether it proceeds via an S_N1 or S_N2...
