Dielectric Constant of Solutions. 0000023004 00000 n 0000051202 00000 n 0000006607 00000 n These metrics are regularly updated to reflect usage leading up to the last few days. It is also important to note that it is possible to have the existence of polar bonds within the nonpolar molecule but due to the symmetrical structure of molecule the polarity gets cancels out with each other. If there is a difference in the electronegativity between atoms of a molecule the polarity in it rises. 0000013337 00000 n In this article, I will answer this question and will cover the surrounding topics too. But instead of having the polar bonds C-H in hexane molecule, due to the asymmetrical shape of hexane molecule, the polarity of these bonds gets canceled by each other and makes the hexane a nonpolar molecule.
