complete the electron‑pushing mechanism for the reaction by drawing the necessary organic structures and curved arrows for each step. make sure to include all nonbonding electron pairs. - Step 1: treatent wth NaBH4, Add curved arrows for lhe frst slep. Treat Na" as a spectator ion: - Step 2 treatment wth DOO Add curved arrows for the second step. Do not snow Na+ counter ion. - Final product (draw the products of the last step. hint organic and one iorganic species. including all nonbonding electron pairs, Do not snow Na+ counter ion.
