Carbons 1 and 4 of 1,3-cyclopentadiene are equivalent and give the same carbocation on protonation. Likewise, Carbons 2 and 3 are equivalent. Write the structure of the carbocation formed by the protonation of C-2 or C-3 to verify that it is not allylic and therefore not as stable as the one formed by the protonation of C-1 or C-4.
