The correct Answer is:
To find the homologue of ethyl propanoate, we need to understand what a homologue is. Homologues are compounds that have the same functional group but differ by a CH2 unit (or one carbon atom). ### Step-by-Step Solution: 1. **Identify the Structure of Ethyl Propanoate**: - Ethyl propanoate is an ester with the structure derived from propanoic acid and ethanol. - Its chemical formula is C5H10O2, and it can be represented as CH3CH2COOCH2CH3. 2. **Determine the Functional Group**: - Ethyl propanoate has an ester functional group (-COO-). 3. **Identify the Homologous Series**: - To find the homologue, we will either add or remove a CH2 group (which corresponds to adding or removing one carbon atom). - Adding one carbon atom will give us ethyl butanoate (C6H12O2). - Removing one carbon atom will give us ethyl ethanoate (C4H8O2). 4. **List the Possible Homologues**: - The possible homologues based on the addition or subtraction of one carbon atom are: - Ethyl butanoate (adding one carbon) - Ethyl ethanoate (removing one carbon) 5. **Select the Correct Homologue**: - Since we are looking for the homologue that retains the ethyl group and differs by one carbon, the correct answer is ethyl butanoate. ### Final Answer: The homologue of ethyl propanoate is **ethyl butanoate**.
