We're being asked why are the molecules of hydrocarbons nonpolar.
We will have to calculate the electronegativity difference of the elements forming the bond:
(ΔEN) Bond Classification
Zero (0.0) Pure Covalent
Small (0.1 – 0.4) Nonpolar Covalent
Intermediate (0.4 – 1.7) Polar Covalent
Large (Greater than 1.7) Ionic
Calculate the electronegativity difference and classify each compound:
Why are the molecules of hydrocarbons nonpolar?
a. the electron pair is shared almost equally in all the bonds.
b. the intermolecular attractions are strong.
c. all the bonds are single covalent bonds.
d. van der Waals forces overcome polarity
