Question

Which one of the following molecules is polar? PBr5 CCl4 BrF5 XeF2 XeF4

Answer 1

Have you tried drawing out the electron dot diagram for them?

Answer 2

PBr5 is polar.
CCl4 is nonpolar

Answer 3

If you draw them out and they have lone pairs then that means that they are polar.

Answer 4

The answer is BrF5, but i don;t know why

Answer 5

BrF5 XeF2 XeF4 they all have lone pairs in central atom, why BrF5 is polar while the rest are not?

Answer 6

@musiclover777 is correct

Answer 7

the first 2 the dipole charges cancel each other out, resulting in a non-polar molecule
the last one it's impossible to balance the dipoles with 5 Fs, resulting in a polar molecule
