To determine the expected hybridization around the central atom, let's first draw the lewis structure for the molecules or ions that we are considering.
00:09
For this phosphorus pentafluoride, we see that there are five electron groups surrounding the phosphorus.
00:19
They are all bonding electron groups.
00:21
Five electron groups corresponds to a dsp3 hybridization.
00:25
For the next one, we have sulfur tetrafluoride.
00:31
And if we count up the number of valence electrons, they'll be 34.
00:36
But 34 valence electrons, after satisfying the octet, we have an extra pair of electrons that we will put on the sulfur.
00:44
So now there are five electron groups surrounding the sulfur...
