Using electronegativity values, classify each of the following bonds as nonpolar covalent, polar covalent, or ionic
O - K, Cl - As, N - N, C - H
Bond
Difference in Electronegativity
Type of Bond
O - K
3.5 - 0.8 = 2.7
ionic
Cl - As covalent
3.0 - 2.0 = 1.0
polar
N - N covalent
3.0 - 3.0 = 0.0
nonpolar
C - H covalent
2.5 - 2.1 = 0.4
nonpolar
