Questions and Answers

Which molecule has a higher dipole moment, NH3 or NF3?

  • NH3, because it has a lower number of lone pairs.
  • NF3, because the electronegativity of F is greater than N. (correct)
  • NH3, because the electronegativity of N is greater than H.
  • NF3, because it has a symmetric shape.

    • What is the shape of both NH3 and NF3 molecules?

  • Pyramidal (correct)
  • Linear
  • Tetrahedral
  • Square planar

    • How does the electronegativity difference between atoms affect the dipole moment?

  • It determines the direction of the dipole moment. (correct)
  • It increases the bond angle.
  • It reduces the number of lone pairs.
  • It decreases the molecule's polarity.
