We want to draw the lewis dot structure, determine the geometry, determine whether or not it's polar, find the hybridization around each central atom, and then draw the valence bond structure with overlapping orbitals.
00:18
And so for i have five, we'll start with the lewis dot structure.
00:21
So we have i with its five fs, and then i will have a lone pair, and then each of these.
00:34
Fs will have three loan pairs.
00:44
And so the g -o -sis is going to be square pyramidal.
00:52
This is going to be polar due to the loan pairs on i.
00:57
The hybridization is going to be sp3d2 because it has six total electron groups and we'll draw the valence bond structure.
01:30
And so we have all of the p -orbitals on f and then the sp3d2 orbitals on i.
01:40
So now letter b, we have ch2, ch3, ch3.
01:47
And so we'll start with the lewis dot structure.
02:01
And so this is going to have two different geometries because we have three central atoms.
02:06
So it will be trigonal planar around these two cs that have that double bond.
02:15
And then tetrahedral around this last c...
