A chemistry grad student proposes the following synthesis for a target compound: (Step 1) (Step 2) (Step 3) A (Step 4) (Step 5) 1) Mg 2) \( \mathrm{CO}_{2} \) (Step 6) B A fellow grad student looks at the procedure and notices mistakes in the planned route either incorrectly planned reactions, or reactions that will not produce the desired result. a) Identify all mistakes in this proposed synthesis. List each step and explain why it will not work/proceed as planned. b) Revise the synthesis to produce the desired compound. If the above step works as planned, do not change it-only modify steps that are incorrect as written. You may add steps if necessary.
