Which compound is identified as ethyl butanoate?

• A. CH₃-CH₂-CH₂-C=O-O-CH₂-CH₃
• B. CH₃-CH=CH-C=O-CH₂-CH₃
• C. CH₃-C=O-O-CH₂-CH₃
• D. CH₃-CH₂-C=O-CH₃

Answer: (A)

Ethyl butanoate is an ester derived from butanoic acid and ethanol. The structure of ethyl butanoate can be represented as CH₃-CH₂-COO-CH₂-CH₃. In this compound, the "ethyl" part comes from the ethanol (CH₃-CH₂-OH), and the "butanoate" part comes from the butanoic acid (CH₃-CH₂-CH₂-COOH). In option A, the structure CH₃-CH₂-CH₂-C=O-O-CH₂-CH₃ clearly shows the butanoate component (CH₃-CH₂-CH₂-C=O), indicating that there are three carbon atoms in the butanoate chain leading up to the carbonyl (C=O) group. The presence of the -O-CH₂-CH₃ indicates that an ethyl group is attached to the oxygen, confirming that this structure is indeed ethyl butanoate. The other options do not correctly represent ethyl butanoate either due to the wrong arrangement of carbon or oxygen atoms, or the improper attachment of the ethyl or butanoate components, leading them to be
