Among the following molecules, the one which has a permanent dipole moment: He2, XeF2, CH4, N2?
Understand the Problem
The question is related to chemical properties, specifically about molecules with permanent dipole moments and electronic repulsions. It requires understanding of molecular structure and bonding in chemistry.
Answer
CH4
The molecule with a permanent dipole moment is CH4.
Answer for screen readers
The molecule with a permanent dipole moment is CH4.
More Information
CH4 (methane) is nonpolar due to its symmetrical tetrahedral shape, so it does not have a permanent dipole moment. XeF2 is also nonpolar due to its linear shape, while He2 and N2 are nonpolar molecules.
Tips
A common mistake is assuming that CH4 has a dipole moment. Its symmetrical shape results in the cancellation of any dipole moments.
