What is is krf2 polar or nonpolar?

Krypton difluoride (KrF₂) is a polar molecule.

Here's why:

• Molecular Geometry: KrF₂ has a linear molecular geometry with Krypton (Kr) as the central atom and two Fluorine (F) atoms bonded to it.

• Electronegativity Difference: Fluorine is significantly more electronegative than Krypton. This means Fluorine pulls the shared electrons in the Kr-F bond more strongly towards itself, creating a dipole%20moment in each Kr-F bond.

• Vector Sum of Dipole Moments: While the molecule is linear, each Kr-F bond possesses a dipole moment pointing towards the Fluorine atom. These bond dipoles are oriented 180° relative to each other. The magnitude of the dipole moments in both bonds are equal. Therefore they don't cancel each other. The presence of net dipole moment makes the molecule polar.
