The correct option is An ester and water.
Explanation
The reaction described is known as esterification. This is a fundamental organic reaction in which a carboxylic acid reacts with an alcohol in the presence of an acid catalyst to form an ester and water.
Reaction Analysis:
- Reactants: The reaction involves Ethanoic acid (CH3COOH), which is a carboxylic acid, and Ethanol (C2H5OH), which is an alcohol.
- Mechanism: In the presence of an acid catalyst (such as concentrated sulfuric acid), a condensation reaction occurs. The carboxylic acid loses a hydroxyl group (-OH) and the alcohol loses a hydrogen atom (-H).
- Products: These eliminated groups combine to form water (H2O). The remaining organic fragments bond to form Ethyl ethanoate (CH3COOC2H5), which is an ester. Esters are characterized by their sweet, fruity odors.
- Chemical Equation:
CH3COOH + C2H5OH ⇌ CH3COOC2H5 + H2O
Key Takeaway: Esterification is the process of forming an ester and water by heating a carboxylic acid with an alcohol in the presence of a catalytic amount of strong acid.
