Ether can be dried over sodium, but not alcohol. Why?

Text Solution

Verified by Experts

Alcohol contains acidic hydrogen and so reacts with sodium metal and releases hydrogen. `2C_2H_5OH + 2Na rarr 2C_2H_5ONa + H_2`
  Ether has no -OH group and does not react with sodium metal. Hence other can be dried over sodium, but not alcohol.
