Which of the following liquids has the lowest enthalpy of vaporization? A) C₄H₁₀ B) C₅H₁₂ C) C₆H₁₄ D) C₇H₁₆ E) C₈H₁₈

Question

Quizplus · Accepted Answer

The lower the enthalpy of vaporization, the easier it is for a liquid to evaporate. As the molecular weight (MW) of a liquid increases, the enthalpy of vaporization typically increases as well. The MW of the liquids in the options increases from A to E. Therefore, option A with the lowest MW will have the lowest enthalpy of vaporization.
