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 sn1 or sn2 mechanism.

To find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? a) when more work was done, the couch was moved the same distance. b) when more work was done, the couch was moved less. c) when more work was done, the couch was moved further. d) when more work was done, the couch wasn't moved at all.
