Question

What is the first step in the treatment with NaBH₄? (Curved arrows should be added)

1) Add Na as a spectator ion
2) Add curved arrows
3) Treat with NaBH₄
4) Cannot be determined

Answer 1

The first step in the treatment with NaBH₄ is to add Na as a spectator ion.

Step-by-step explanation:

The first step in the treatment with NaBH₄ is to add Na as a spectator ion. This means that Na does not directly participate in the reaction and is only present to balance the charge. The curved arrows represent the movement of electrons in the reaction mechanism. So, the correct answer is 1) Add Na as a spectator ion.
