Which pair of compounds can be distinguished by sodium metal?

  1. Aethanol and propan-1-ol
  2. Bphenol and benzyl alcohol
  3. Cmethoxybenzene and ethoxyethane
  4. Dbutan-2-ol and ethoxyethane

Answer: D

Compounds with an O-H liberate with sodium; ethers do not. Only the pair butan-2-ol (reacts) and ethoxyethane (does not) differs in behaviour; the other pairs behave alike.
