Nonpolar compounds are compounds that do not have slightly negative and positive charges within the compound. The electronegativity differences of nonpolar compounds are between 0 and 0.2. All hydrocarbons without major subgroups are nonpolar compounds. Sometimes the electronegativities within a compound are such that one would classify the compound as being polar covalent, yet the compound acts nonpolar because the compound is symmetrical. In such a situation, the outward pulling in opposite directions with equal forces cancel each other out.
