PF3Cl2 - Phosphorus Trifluoride Dichloride:
First draw the Lewis dot structure:
Electron geometry: trigonal bipyramidal. Hybridization: sp3d
Then draw the 3D molecular structure using VSEPR rules:
Don't put the chlorine atoms directly across from each other;
the fluorine atoms are more electronegative than chlorine and will repel each other more strongly.
Click and drag the molecle to rotate it.
Decision:
The molecular geometry of PF3Cl2 is trigonal bipyramidal with asymmetric charge distribution on the central atom.
Therefore PF3Cl2 is polar.
This is somewhat of a rare molecule, but here is one similar:
