Question

Upon treatment with a catalytic amount of an acid such as HCl in ethanol, 1,4-pentadiene undergoes rearrangement to an isomer that is more stable than the starting compound. Draw the structure of this isomer and the mechanism by which it is formed. Use the curved arrow formalism to depict all bond-forming and bond-breaking steps, and show all intermediates.
