Q. It is \(f_2\) polar.

Q: Is \mathrm{F_2} polar or nonpolar?

\mathrm{F_2} is nonpolar. It is a diatomic molecule with two identical F atoms, so the electronegativity difference is zero and bond dipoles cancel.

Q: How do electronegativity values determine polarity for \mathrm{F_2} ?

\chi(\mathrm{F}) = \chi(\mathrm{F}) , so \Delta \chi = 0 . With no electronegativity difference, the bond is effectively nonpolar, making the molecule nonpolar.

Q: What molecular geometry features matter for polarity, and does \mathrm{F_2} have them?

Geometry matters for polyatomic molecules. For \mathrm{F_2} , it is linear by default (diatomic), and identical ends ensure symmetry and cancel any dipole.

Q: Can a bond be polar inside a nonpolar molecule like \mathrm{F_2} ?

Not for \mathrm{F_2} . Because the bonded atoms are identical, the \mathrm{F-F} bond has no electronegativity-driven polarity, so there isn’t a bond dipole to cancel.

Q: How do I quickly decide polarity for diatomic molecules like \mathrm{F_2} ?

If both atoms are the same, e.g., \mathrm{F_2} , \mathrm{O_2} , \mathrm{N_2} , the molecule is nonpolar. If different, e.g., \mathrm{HF} , it can be polar.

Answer

\(f_{2}\) is polar.

Quick check: \(F_{2}\) is a diatomic molecule with identical atoms, so the dipole moments cancel. In other words, there is no net molecular dipole moment.

Final result: \(f_{2}\) is nonpolar.

Detailed Explanation

Step 1: Clarify what “F2” means

Interpreting the symbol as F₂, that means a molecule made of two atoms of fluorine bonded together.

Step 2: Determine the shape and symmetry

For a diatomic molecule like F₂, there are only two atoms. A two-atom molecule always has a straight line structure. The molecule is therefore symmetric: the electron distribution and structure are the same on both sides of the bond.

Step 3: Check whether the bond has a dipole

The polarity of a chemical bond depends on electronegativity differences. Fluorine and fluorine have the same electronegativity, so the bond dipole moments cancel because they are equal and opposite.

Step 4: Decide molecular polarity

Molecular polarity requires a nonzero net dipole moment. For F₂, the net dipole moment is zero.

Final answer: No, F₂ is not polar.

General Chemistry FAQs

Is \( \mathrm{F_2} \) polar or nonpolar?

\( \mathrm{F_2} \) is nonpolar. It is a diatomic molecule with two identical F atoms, so the electronegativity difference is zero and bond dipoles cancel.

Does \( \mathrm{F-F} \) have a dipole moment?

No net dipole moment. While each bond has an internal dipole concept, in \( \mathrm{F_2} \) the dipoles are equal and opposite in a straight diatomic geometry, giving zero net dipole.

How do electronegativity values determine polarity for \( \mathrm{F_2} \)?

\( \chi(\mathrm{F}) = \chi(\mathrm{F}) \), so \( \Delta \chi = 0 \). With no electronegativity difference, the bond is effectively nonpolar, making the molecule nonpolar.
