Which gas is released when ethanol is oxidised to ethanoic acid using an oxidising agent?
-
A.
Oxygen
-
B.
No gas is released.
-
C.
Hydrogen
-
D.
Carbon dioxide
Correct Answer:
B. No gas is released.
Explanation:
When ethanol ($C_{2}H_{5}OH$) undergoes oxidation to form ethanoic acid ($CH_{3}COOH$) using an oxidizing agent like alkaline potassium permanganate or acidified potassium dichromate, no gas is released during the chemical reaction. This process involves the addition of oxygen and the removal of hydrogen from the ethanol molecule. Unlike the reaction of ethanoic acid with carbonates or active metals, which produces carbon dioxide or hydrogen gas respectively, this specific transformation is a controlled oxidation of a functional group that does not result in the evolution of any gaseous byproducts. Therefore, the correct observation is that no gas is released.
