Okay, it looks like you've got the right idea answering this question, however you're only supposed to identify a single polar covalent bond, not all of them, and so i think that's where you went wrong, but nevertheless let me sketch out the structures here.
00:17
It wants you to identify a single polar covalent bond.
00:22
In fact, carbon -hydrogen bonds are not classified as polar covalent, they're purely covalent, this is purely due to the electronegativity difference between the atoms.
00:31
Carbon and oxygen are very different in terms of electronegativity.
00:36
Carbon and hydrogen are essentially the same, which is why they form covalent bonds.
00:41
Carbon and oxygen are so different as to form polar covalent bonds.
00:45
So you would say yes, like you did, the carbon is positively charged, and like you did, the oxygen is negatively charged, but you would not put anything in the box for hydrogen or the other hydrogen, right, because these are not polar covalent bonds...
