When ethanol reacts with ethanoic acid in the presence of concentrated H2SO4, ______ is produced.

Correct option is C

The correct answer is (C) Ester

Explanation:
• When an alcohol (such as ethanol) reacts with a carboxylic acid (such as ethanoic acid) in the presence of an acid catalyst (like concentrated sulfuric acid), an ester is formed.
• This specific chemical reaction is called an esterification reaction.
• In this exact case, ethanol (C2H5OH) and ethanoic acid (CH3COOH) react to form ethyl ethanoate (CH3COOC2H5), which is an ester, along with a molecule of water.
• The concentrated H2SO4 acts as a dehydrating agent, removing water to push the equilibrium toward ester formation.

Information Booster:
• Properties of Esters: Esters are known for their sweet, fruity smells. Because of this, they are extensively used in the manufacturing of perfumes, synthetic flavorings, and cosmetics.
• Saponification: The reverse or breakdown of esters using a strong base (like NaOH) yields the alcohol and the sodium salt of the carboxylic acid, a process used to make soap.

Additional Knowledge:
• Option A (Aldehyde): Formed by the partial oxidation of primary alcohols, not by reacting alcohols with acids.
• Option B (Ketone): Formed by the oxidation of secondary alcohols.
• Option D (Alcohol): Ethanol itself is the alcohol in the reactant phase; it is not the product of this combination.
