STEP 2:

Complete the mechanism for the dissolving metal reduction of the alkyne by drawing the appropriate curved arrows in each box and the final product in the final box. A solvated electron is represented by \( \bullet \mathrm{Na} \). All structures and necessary electrons are provided. Draw the final product of the reaction in the last box. 1st attempt Part 1 (2 points) See Periodic Table Draw the curved arrows in the reaction between the solvated electron \( (\bullet \mathrm{Na}) \) and alkyne to generate the next structure. \( \theta \rightarrow \cos ^{20} \) \( \mathrm{Na} \cdot \) A solvated electron adds to the intermediate shown in box 3 of part 1 , as shown here: The product of this addition is shown in box 1 below. Draw the curved arrow mechanism showing how this compound would interact with ammonia, then draw the final product of this sodium ammonia reduction of an alkyne. (1) Draw the currved arrow mechanism showing proton abstraction between the intermediate and \( \mathrm{NH}_{3} \).
