Look at your EN table and polarity range reference. Consider the bond between Br and O. What is the EN difference and classify the bond polarity.

• 0.7; polar covalent

• 0.7; nonpolar

Answer explanation

subtract the smaller EN value from the larger value (3.5-2.8). 0.7 falls in the "polar covalent" category, if you look at your ranges.
