Ethanol reacts with ethanoic acid in the presence of concentrated sulphuric acid. What is this fruity-smelling reaction called?
ADehydrogenation
BSaponification
CDecarboxylation
DEsterification
Answer & Solution
Correct answer: D. Esterification
1. An alcohol reacting with a carboxylic acid forms an ester, which has a fruity odour.
2. The reaction that forms an ester is called esterification.
3. Saponification makes soap, decarboxylation removes CO₂, and dehydrogenation removes hydrogen, so these are wrong.
4. Hence the reaction is esterification.
