Question on problem 11 on page 782

Okay I have a question.... I'm doing problem 11 on page 782, I got the final answer correct but when I was adding the hydrogen on the oxygen on the final step I used pyrinide, but the solutions guide says to use HCl. Is there a diffence in using a strong acid versus a mild acid?

    Either would be fine.

    In the paragraph above Problem 11 (p. 782), it says that, "a weak acid (one that will not react with the triple bond, such as pyridinium ion shown here) is added to the reaction mixture to protonate the alkoxide ion."

    If it ends up being acceptable to use a strong acid, such as HCl, what prevents the reaction between the strong acid and the triple bond from occurring?
