Quick Homework question... Chemistry. Is what I already have correct?
Which of the following molecules has a net dipole movement?
a) XeF4
b) ICl3
c) Ge(CH2CH3)4
d) None of these
MY ANSWER: When I did this question, I came my answer, I got that A had C had no net dipole movement and therefore came up with the fact that choice B had net dipole movement based on lewis structures. Is this correct?
Thanks for your help in advance! Appreciate it!

You are correct.
Use the VSEPR model to answer
a) Square planar, all surrounding elements the same - no net dipole.
b) T-shaped. This will have a net dipole, as you identified
c) Having identified one element with a net dipole and another without, the answer to this is clearly no-dipole. However, it makes sense if you think of germanium being in the same group as carbon, then the geometry ought be tetrahedral with all surrounding groups identical - no net dipole
