Orcinol react with metallic sodium
WebSodium and air reaction. When a sodium metal piece is put in the air, there are several reactions occurring as a chain. Air contains nitrogen, oxygen, carbon dioxide, water vapor and more gases. Sodium reacts with oxygen gas and produce sodium oxide (Na 2 O) which is a strong basic oxide. Na (s) + O 2 (g) → Na 2 O (s) WebSodium also reacts with polycyclic aromatic hydrocarbons via one-electron reduction. With solutions of naphthalene, it forms the deeply coloured radical sodium naphthalene, which is used as a soluble reducing agent: C 10 H 8 + Na → Na + [C 10 H 8] −•
