molecular polarity

Why is CO more polar than BO? This was on a workshop review worksheet.

It is more polar because there is a greater difference in electronegativity between the C-O bond than the B-O bond.

The electronegativity difference between the two is greater than that of the BO bond. You would either be able to tell this directly from numerical subtraction if the electronegativities were given to you, or by looking at the periodic table and seeing that C and O are farther from each other than B and O, and all are in the same period.

The reason that CO is more polar than BO is due to the electronegativity difference between both elements. CO has a great electronegativity difference, so it is more polar than BO.
