Polar Covalent Bonds vs. Ionic Bonds Some bonds are acceptable to write as a covalent bond or an ionic bond, as in the following example: or The electronegativity difference is 1.5 , so it is on the cusp of polar covalent and ionic, according to just one method used for determining electronegativity values. So, the absolute difference in electronegativity is to be taken with a grain of salt. Question: Arrange the following in the order of DECREASING BOND POLARITY for the bonds between dissimilar atoms: a.
,1>3>5>2>4
1 . 2 . KCl b.
3>1>5>4>2
c.
1>3>2>5>4
d.
5>4>2>1>3
e.
3>1>2>5>4
