In the reaction of 2-chloro-2-methylpropane with [tex]\mathrm{AgNO}_3[/tex] and ethanol, one product (shown below) is formed via an [tex]\mathrm{S}_{\mathrm{n}} 1[/tex] pathway, as shown below.

However, a second product can also form. What is the structure of the second compound formed, and by which mechanism is it formed? Hint: Of the four possible reaction pathways that you've learned so far [tex]\left(\mathrm{S}_{\mathrm{n}} 2, \mathrm{~S}_{\mathrm{n}} 1\right.[/tex], E2, and E1), two of them involve the same intermediate.
