Question: Give two requirements that should be satisfied for a molecule
Give two requirements that should be satisfied for a molecule to be polar. Explain why CF4 and XeF4 are nonpolar compounds (have no net dipole moments), whereas SF4 is polar (has a net dipole moment). Is CO2 polar? What about COS? Explain.
