There's a question about it: CBr4 SO3 XeF4 ClF5 PBr5 which one is polar? Click to expand... 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. Upvote 0 Downvote

The answer is ClF5 since you have an extra pair of electrons on the chlorine. These pair of electrons create unequal sharing of electron. Upvote 0 Downvote
