which one is polar?

You know your VSEPR?

CBr4 - tetrahedral
SO3 - trigonal planar
XeF4 - square planar
ClF5 - square pyramidal
PBr5 - trigonal bipyramidal

Know how these molecules look in 3-d, and see if the group's polarity cancels each other out. ClF5 is the only molecule where there is a dipole.

Is answer ClF5?

The correct way is to draw their lewis structures and look at the distribution of electrons. The answer is ClF5 since you have an extra pair of electrons on the chlorine. These pair of electrons create unequal sharing of electron.

yes, the answer is ClF5, thank you for all of you!!
