What is the correct molecular shape for NF3?


Wiki User

Trigonal Pyramidal - 107.5 degrees

It has 3 bonds and one lone pair.

With all 4 elements (the 3 covalent bonds plus the lone pair) you would think it was Tetrahedral, with 109.5 degrees between them, but because the lone pair is there, it pushes the other bonding electrons closer together and thus you have a smaller angle of 107.5 degrees and the different shape.
