In this problem, we're looking at ketone functional groups.
00:05
So a ketone is a kind of functional group that involves a carbonyl, so double bond between carbon and oxygen.
00:14
And for this specific functional group, there is some kind of carbon group on either side.
00:20
So often you'll see those drawn as r and r prime, where r and r prime are not hydrogens.
00:33
So then if we look at our hybridization, remember that we're looking at sigma bonds and electron pairs.
00:45
And also keep in mind, a single bond has one sigma bond and zero pi bonds.
00:52
And a double bond has one sigma bond and one pi bond.
00:56
So here we have one, two, three sigma bonds and zero electron pairs.
01:07
So that means we have sp2 geometry.
01:13
And we have a polar carbon -oxygen bond.
01:21
So if we look at answer a, they contain a carbonyl group that exhibits sp hybridization.
01:29
So we said it's sp2...
