Why are the molecules of hydrocarbons nonpolar? the electron pair is shared almost equally in all the bonds. the intermolecular attractions are strong. all the bonds are single covalent bonds. van der waals forces overcome polarity?

Hydrocarbon molecules are composed of a carbon with hydrogen.  When it comes to electronegativity, not one of these elements form polarity. When you have a huge difference in electronegativity, O-H,  then polarity is created.Both elements are too close in their electronegativity, thus, share electrons equally.

The answer is A: The electron pair is shared almost equally in all the bonds.

Explanation:

Polarity means formation of two poles i.e a partial positive charge pole and a partial negative charge pole. Such partial charges develop only when the two bonded atoms have difference in electronegativity. More electronegative atom attracts the shared pair of electron resulting in formation of partial negative charge on it. In case of hydrocarbons both carbon and hydrogen have not much difference in their electronegativity and thus the bond becomes non polar.

i think its 100.

hope this !
