Consider the reaction. 1. \( \mathrm{NaBH}_{4} \) 2. \( \mathrm{D}_{2} \mathrm{O} \) Complete the electron-pushing mechanism for the reaction by drawing the necessary organic structures and curved arrows for ach step. Make sure to include all nonbonding electron pairs. Step 1: Add curved arrows for the first step, treatment with \( \mathrm{NaBH}_{4} \). Treat \( \mathrm{Na}^{+} \)as a spectator ion. Step 2: Add curved arrows for the second step, treatment with \( \mathrm{D}_{2} \mathrm{O} \). Do not show the \( \mathrm{Na}^{+} \)counter ion. Step 3: Draw the final products of the last step (one organic and one inorganic species), including all nonbonding electron pairs. Do not show the \( \mathrm{Na}^{+} \)counter ion.
