RMgX+CO2→dry etherY→H3O+RCOOH\mathrm{RMgX + CO_2 \xrightarrow{dry\ ether} Y \xrightarrow{H_3O^+} RCOOH}

What is Y in the above reaction?

  1. A.(RCOO)2Mg\mathrm{(RCOO)_2Mg}
  2. B.RCOO− Mg+X\mathrm{RCOO^-\,Mg^+X}✓
  3. C.R3CO− Mg+X\mathrm{R_3CO^-\,Mg^+X}
  4. D.RCOO− X+\mathrm{RCOO^-\,X^+}

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
