MDCAT Chemistry MCQ #1754

  1. Question 1

    Q1. A diatomic molecule has a dipole moment of 1.2 D and a bond length of 1.0 Angstrom. Calculate the fractional charge on the atoms.

    • A) 0.12
    • B) 0.25
    • C) 0.50
    • D) 0.75

    Answer: 0.25

    Explanation: Fractional charge is calculated as observed dipole (1.2) divided by calculated dipole (4.8). 1.2/4.8 equals 0.25. 0.50 suggests a much higher dipole.
