Answer
The resulting product is (E)-4-ethoxypent-2-ene.
Work Step by Step
First, the given reactant undergoes a first-order ionization which leads to the formation of a resonance-stabilized carbocation. As the resulting carbocation is symmetric, only one product can be obtained after the EtOH attack followed by deprotonation, this being (E)-4-ethoxypent-2-ene, as shown below.
