polarity in covalent compounds depends on the difference in electronegativities of teh elements.
Electronegaitivity of:
C = 2.550
O = 3.440
Difference in electronegativity = 0.89
H = 2.200
Br = 2.960
Difference in Electronegativity = 0.76
So. CO is more polar

Well, let's see:
CO (Carbon monoxide) has the two atoms tied together with a covalent bond (shared electrons). The charge is fairly evenly distributed across the molecule.
HBr (Hydrogen Bromide) has the atoms tied together by an ionic bond (think of it as acting like static electricity): H+ and Br-. The charge is not evenly distributed across the molecule.
So, what does "polar" refer to, then?
