Ethanol is converted into ethoxy ethane,
- A by heating excess of ethanol with conc. \( \mathrm{H}_{2} \mathrm{SO}_{4} \) at \( 140^{\circ} \mathrm{C} \).
- B by heating Ethanol with excess of conc. \( \mathrm{H}_{2} \mathrm{SO}_{4} \) at \( 443 \mathrm{~K} \)
- C by treating with conc. \( \mathrm{H}_{2} \mathrm{SO}_{4} \) at room temperature
- D by treating with conc. \( \mathrm{H}_{2} \mathrm{SO}_{4} \) at \( 273 \mathrm{~K} \).
Answer & Solution
Correct Answer
(A) by heating excess of ethanol with conc. \( \mathrm{H}_{2} \mathrm{SO}_{4} \) at \( 140^{\circ} \mathrm{C} \).
Step-by-step Solution
Detailed explanation
Ethanol is converted into ethoxy ethane at \( 413 \mathrm{~K} \).
Due to the presence of lone pairs of the electron in oxygen, ethanol acts as a weak base, it reacts with strong mineral
acids.
