Correct Answer: Option C
Explanation

The compound CH\(_3\)CH\(_2\)COOCH\(_2\)CH\(_3\) is an ester. The IUPAC naming for esters follows the format alkyl alkanoate

  • The alkyl portion comes from the alcohol-derived part (the carbon chain attached to the single-bonded oxygen, −O−CH\(_2\)CH\(_3\)), which has two carbon atoms, making it an ethyl group.
  • The alkanoate portion comes from the carboxylic acid-derived part (the carbon chain including the carbonyl group,CH\(_3\)CH\(_2\)COO−), which has three carbon atoms (eth- plus a methyl group), making it a propanoate group (from propanoic acid).
  • Combining these parts gives the name ethyl propanoate. - option C

There is an explanation video available below.
