Is the molecule PBr3 polar or nonpolar polar nonpolar Is the

Is the molecule PBr_3 polar or non-polar? polar non-polar Is the molecule SiF_4 polar or non-polar? polar non-polar

Solution

1. PBr3 is a polar molecule. Its trigonal pyramidal geometry does not allow the bond dipoles to cancel out, leaving the molecule with a net dipole. So, the correct answer is polar.

2. Silicon tetrafluoride, or SiF4, is a non-polar compound. The flourine\'s negative dipoles cancel each other out. So, the correct answer is non-polar compound.
