Question

In 3-4 sentences, identify how the geometric structure of NF3 is different than that of NF4+. Explain how the geometry affects the ability of the molecules to experience a dipole effect. (I did the Lewis diagrams for both but I don't know what to do after that)

Answer 1

NF3 is trigonal pyramidal; therefore, it is not symmetrical in three dimensions. NF4^+ is tetrahedral and is not polar because the N-F polar bonds balance each other. That is not true for NF3.
