#"Non-polar bond"#: #H-H# in #"dihydrogen........."#

Explanation:

#"Non-polar bond"#: #H-H# in #"dihydrogen........."#; and #C-C# in #H_3C-CH_3#. Because there is no difference in electronegativity between the bonding atoms, there can be no polarity, nor charge separation, and hence a non-polar bond results.

#"Polar bond"#: #OH_2#, and #H-X#, there is charge separation between the oxygen/halogen and hydrogen atoms. The more electronegatve oxygen or halogen atom tends to polarize electron density towards itself. The result?

#"Bond polarity"#, which we could represent as: #""^(delta-)X-H^(delta+)# or #""^(delta+)H-O^(delta-)-H^(delta+)#.
