The correct answer is a) anhydrous calcium chloride,, because H2SO4 is already reacting with ethanol
Calcium chloride (CaCl2) is often used to dehydrate ethyl ethanoate because it forms a complex with water, removing it from the reaction mixture. Concentrated sulfuric acid (H2SO4) can also dehydrate alcohols, but it's more likely to cause unwanted side reactions with esters like ethyl ethanoate. Additionally, CaCl2 is easier to handle and less corrosive compared to concentrated sulfuric acid.
Anhydrous calcium chloride is used to remove the water present in the mixture.
The answer is A.
