In other words, the electronegativity difference of these bonds is very less. Because the difference in electronegativity between the C and H atoms is less than 0.5 we consider there to be a non-polar bond.

As a result, they are nonpolar molecules by nature (examples: CO2, SO3). Butane (C4H10) is a nonpolar molecule because the difference in electronegativity between carbon(2.55) and hydrogen(2.2) is less than 0.5, which is way lower to form a polar bond according to the Pauling scale. Food Res. VII. XXVII. Its non-polarity tells us that the only intermolecular forces it has are London dispersion forces.
