MDCAT Chemistry MCQ #3952

  1. Question 1

    Q1. A researcher compares the boiling points of n-pentane and neopentane, finding neopentane boils at a lower temperature. This anomaly is due to:

    • A) Higher molecular mass
    • B) Stronger Hydrogen bonding
    • C) Greater surface area
    • D) Spherical shape and less surface area

    Answer: Spherical shape and less surface area

    Explanation: Neopentane has a lower boiling point due to its spherical shape and less surface area. n-Pentane is tempting because it has the same mass.
