Q: Molecules like H₂, O₂, N₂,C1₂ and Br₂ have______ Dipole moments.
  • A. Very high
  • B. Very low
  • C. Zero
  • D. High
Correct Answer: Option C - For diatomic molecules, there is only one bond so its bond dipole moment determines the molecular polarity. Homonuclear diatomic molecules such as H₂, O₂, N₂, and Br₂ have no difference in electro negativity so their dipole moment is zero.
C. For diatomic molecules, there is only one bond so its bond dipole moment determines the molecular polarity. Homonuclear diatomic molecules such as H₂, O₂, N₂, and Br₂ have no difference in electro negativity so their dipole moment is zero.

Explanations:

For diatomic molecules, there is only one bond so its bond dipole moment determines the molecular polarity. Homonuclear diatomic molecules such as H₂, O₂, N₂, and Br₂ have no difference in electro negativity so their dipole moment is zero.
