  • A Methane
  • B Ethanoic acid
  • C Ethene
  • D Ethyl ethanoate
  • E Carbon tetrachloride
Correct Answer: Option D
Explanation:
I. It is not miscible with water: Ethyl ethanoate (an ester) is non-polar and typically not miscible with water.

II. It has a boiling point of 77°C: The boiling point of ethyl ethanoate is around 77°C, matching the given property.

III. It has a sweet odor: Esters like ethyl ethanoate are known for their sweet, fruity odors.

IV. It is insoluble in sodium hydrogen carbonate solution: This indicates the compound is not acidic, which fits ethyl ethanoate (an ester) since it doesn't contain a carboxyl group in free form.

V. It does not decolorize bromine water: This suggests the compound is not unsaturated (not an alkene like ethene), which is true for ethyl ethanoate, a saturated ester.
