What is the polarity of a Na-Br bond?

nonpolar covalent

definitely polar covalent

likely ionic

slightly polar covalent

slightly ionic

Solutions

Expert Solution

Correct option: likely ionic

Electronegativity of Na on Pauling scale = 0.93

Electronegativity of Br on Pauling scale = 2.96

Difference in electronegativity = (2.96 - 0.93) = 2.03

If the electronegativity difference between atoms participating in a bond is more than 1.8, then such bond is called ionic bond. Hence the polarity of the bond is ionic.
