A polar molecule results from an unequal/unsymmetrical sharing of valence electrons. ; Matthews, M.A. Greater the hydrocarbon portion, more non-polar it becomes. Nonpolar compounds will be symmetric, meaning all of the sides around the central atom are identical - bonded to the same element with no unshared pairs of electrons. Chim.
