This molecule undergoes an E1 mechanism when stirred in methanol. Provide the missing parts of the mechanism by drawing necessary chemical species, curved arrows, formal charges, and lone pairs of electrons in the first two boxes. Draw ONLY the major alkene product of the reaction in the box to the far right (do not draw any byproducts). Note that if you are drawing a hydrogen as part of your mechanism, you need to draw ALL the hydrogens attached to that...

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 (CH3CN). 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.

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 mechanism.
