b] PF3 is polar because it contains polar bonds and is not symmetrical
2. H-N-H bond angle is 107.5 because in space everything is three dimensional. If you looked at a three dimensional molecule of H-N-H, you would see that the angle is greater than 90 degrees. When measured it turns out to be about 107.5 degrees.
consider the molecules PF3 and PF5.
b]is the PF3 molecule polar or is it nonpolar. explain
C] on the basis of bonding principles, predict whether each of the following compounds exists. In each case explain your prediction.
(i) NF5
(ii) AsF5
2. explain why the H-N-H bond angle is 107.5 degrees in NH3.
You need to tell me a little of what you think on these. The last question was a freebie but this one isn't.
hints:
for b, draw the Lewis electron dot structure for PF3 and that will tell you the shape. That will tell you if it is polar or non-polar.
For NF5 and AsF5, go through the Lewis dot structures.
i don't know

PF3 Triangular pryramid shape thus is not symmetric yet PF5 is symmetric thus the molecule is not polar
