What happens when (Write chemical equation in each case)

  1. ethanol is burnt in air?
  2. ethanol is heated with excess cone. H2SO4 at 443 K?
  3. A piece of sodium is dropped into ethanol?

1.When ethanol is burnt in air, it gives CO2, HaO and Heat

C2H5OH + O2 → CO2 + H2O + Heat

2.When ethanol is heated with excess cone. H2S04 at 443K it gives ethene and water.

3.When a piece of sodium is drapped into ethanol, Hydrogen gas is evolved other product is sodium ethoxide.

2C2H5OH + 2Na → 2C2H5ONa + H2↑
