(a)
Interpretation: For the given compounds, major products should be predicted when each of them are treated with Birch condition.
Concept introduction:
- Birch reduction converts
aromatic compound having benzoid ring in to a product 1, 4-cyclohexa diene. - The product having hydrogen atoms attached on opposite end of the molecule
- Birch reduction is the reduction of aromatic rings with sodium , potassium or lithium and an alcohol in liquid ammonia
- Birch reduction is unlike catalytic hydrogenation
- When the benzene with an electron donating group such as alkyl group is treated with Birch reduction, the carbon atom connected to the alkyl group is not reduced. Electron donating effect destabilizes the radical anion.
- When an electron withdrawing groups are used, different regiochemical outcome is observed. Electron withdrawing effect stabilizes the intermediate.
