Ethanol is converted into ethoxy ethane,

Options

  1. Aby heating excess of ethanol with conc. ( H ₂ SO ₄ ) at ( 140^ C ).
  2. Bby heating Ethanol with excess of conc. ( H ₂ SO ₄ ) at ( 443 ~K )
  3. Cby treating with conc. ( H ₂ SO ₄ ) at room temperature
  4. Dby treating with conc. ( H ₂ SO ₄ ) at ( 273 ~K ).

Correct answer

A. by heating excess of ethanol with conc. ( H ₂ SO ₄ ) at ( 140^ C ).

Step-by-step solution

Ethanol is converted into ethoxy ethane at ( 413 ~K ). Due to the presence of lone pairs of the electron in oxygen, ethanol acts as a weak base, it reacts with strong mineral acids.
