Ester naming in acid-alcohol reactions Steps:

• Ethanoic acid provides the "ethanoate" part from its carboxylate group.
• Propanol provides the "propyl" alkyl group from its chain.
• Ester name follows the format: alkyl from alcohol + alkanoate from acid.
• Result: propyl ethanoate, with structure CH₃COOCH₂CH₂CH₃. Why C is correct:
• Follows IUPAC naming convention for esters, where the alcohol's alkyl group precedes the acid's carboxylate name. Why the others are wrong:
• A: Duplicate of C, but listed separately—still correct naming, though not the designated choice.
• B: Swaps groups; uses "ethyl" from acid instead of alcohol.
• D: Swaps groups; uses "ethyl" from acid and "propanoate" from alcohol.

Final answer: C
