Step 1
Which pair of chemicals would produce ethyl pentanoate by esterification?
Answer
To determine which pair of chemicals produces ethyl pentanoate through esterification, we must recognize that esterification involves the reaction between an alcohol and a carboxylic acid.
Ethyl pentanoate is formed from the following components:
- Alcohol: Ethanol (C₂H₅OH)
- Carboxylic Acid: Pentanoic acid (C₄H₈O₂)
In the provided choices:
- Option A: Ethene and pentan-1-ol does not include a carboxylic acid.
- Option B: Ethane and pentanoic acid does not include an alcohol.
- Option C: Ethanol and pentanoic acid is correct, as it includes both the necessary alcohol and acid for esterification.
- Option D: Ethanoic acid and pentan-1-ol does not form ethyl pentanoate because it has different reactants.
Thus, the correct answer is C. Ethanol and pentanoic acid.
