1) H-CEC: Na
2) H;0*

Correct. The acetylide ion functions as a nucleophile and attacks the neutral epoxide ring, and protonation of the
resulting alkoxide occurs with aqueous workup.
Identify the most likely sequence of steps in the mechanism:
Step 1:
nucleophilic attack
Step 2:
protonate
Step 3:
none (only 2 steps)
