SF₅Cl - Sulfur Pentafluoride Monochloride:

First draw the Lewis dot structure:

Electron geometry: octahedral. Hybridization: sp³d²

Then draw the 3D molecular structure using VSEPR rules:
Click and drag the molecle to rotate it.

Decision:
The molecular geometry of SF₅Cl is octahedral with asymmetric charge distribution on the central atom.
Therefore SF₅Cl is polar.

This is a slightly rare molecule, but here is one similar: Sulfur Hexafluoride on Wikipeida.
