The reaction between ethanoic acid and ethanol in the presence of concentrated sulfuric acid produces:
Correct: B
This is an esterification reaction. Ethanoic acid (a carboxylic acid) reacts with ethanol (an alcohol) in the presence of concentrated H2SO4 (as a dehydrating agent and catalyst) to form an ester, ethyl ethanoate, and water. CH3COOH + CH3CH2OH → CH3COOCH2CH3 + H2O.
