This question covers determining hybridization for different atoms in a molecule.
00:05
And to answer this question, we're just going to refer to the images in the textbook that were provided, and we're going to refer to them and indicated atoms with the red arrow.
00:14
We're going to decide what sort of hybridization would we expect to see from these particular atoms.
00:20
So this first example, we've got ch3 -ch double -bonded to ch2.
00:24
So if we were going to draw this out, maybe more neatly over here in blue, we would have it.
00:33
Structure something like this.
00:39
All right.
00:41
And the atom that we want to determine the hybridization of is this one right here.
00:47
And as we can see, this atom has three different electron domains that it is bonding through.
00:57
There are three different places for it to, that it's bonding.
01:01
And one of them is, in fact, a double bond.
01:06
And what do we know when there is a double bond for a carbon atom.
01:11
We know that this will end up being sp2 hybridized.
01:16
And this makes sense.
01:18
We see that we have three different bonding interactions happening.
01:21
One of them is a double bond and two single bonds.
01:23
And we have one s and two b orbitals mixing together to form three valence bonding orbitals.
01:30
And that checks out with the example that we're given here.
01:35
And the next example that we're given.
01:37
We're seeing this ketone here, this dimethyl ketone, and we're trying to determine the trying to determine the hybridization of the carbonyl oxygen...
