It is made up of three different atoms i.e., a carbon (C) atom in the center is bonded to 2 hydrogens (H) atoms and an oxygen (O) atom by single and double covalent bonds respectively. Since glycine lacks an R group it is placed into the "nonpolar" category for the lack of better placement. The dipole moment arises from polarity which basically comes from the difference in electronegativities of the bonded atoms in a molecule. lar nn-p-lr : not polar especially : consisting of molecules not having a dipole a nonpolar solvent Example Sentences Recent Examples on the Web The remaining nonpolar molecules in food - like fats and minerals - are not heated by the microwaves themselves. This is the structure of n-pentane: The molecule is very large, which means that not only are there more London dispersion forces present, but also stronger London dispersion forces.
