Question

What is formed when ethanol reacts with ethanoic acid on warming in the presence of a few drops of concentrated sulphuric acid?

A.

Ethene

B.

Ester

C.

Ethane

D.

Sodium ethoxide

Correct option is B

The correct answer is (b) Ester.
· When ethanol reacts with ethanoic acid in the presence of a few drops of concentrated sulphuric acid (acting as a catalyst), an esterification reaction occurs. This reaction produces an ester along with water.
· The ester formed in this reaction is called ethyl ethanoate with the chemical formula CH₃COOCH₂CH₃.
· This is a characteristic reaction for producing esters, known for their pleasant, fruity odors.
Information Booster:
· Ethene: Formed by the dehydration of ethanol, but not in this reaction.
· Ethane: Not formed in this reaction.
· Sodium ethoxide: Formed when ethanol reacts with sodium, not with ethanoic acid.
