Which of the following statements correctly describe the Birch reduction of aromatic systems (using — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

The Birch reduction breaks aromaticity but stops at the diene stage, unable to reduce the isolated double bonds it creates. The stereoelectronics of the radical anion intermediate dictate that electron-donating groups stabilize the radical at the ortho/meta positions, putting the double bond on the ipso carbon. EWG groups stabilize the ipso carbon, pushing double bonds away.
