Why is CF4 nonpolar?
Understand the Problem
The question is asking about the molecular polarity of carbon tetrafluoride (CF4) and why it is classified as nonpolar despite having polar bonds. To answer this, we need to consider the molecular geometry and symmetry of CF4.
Answer
CF4 is nonpolar due to its symmetrical tetrahedral structure.
CF4 is nonpolar because its tetrahedral geometry allows the four C-F bond dipoles to cancel each other out, resulting in a net dipole moment of zero.
Answer for screen readers
CF4 is nonpolar because its tetrahedral geometry allows the four C-F bond dipoles to cancel each other out, resulting in a net dipole moment of zero.
More Information
CF4 contains polar C-F bonds due to the difference in electronegativity between C and F atoms. However, the molecular symmetry ensures that the sum of the bond dipoles is zero, leading to no overall polarity.
Tips
A common mistake is assuming that the presence of polar bonds always results in a polar molecule. The overall molecular geometry must also be considered.
