Determine if the bonds in the molecule are covalent or ionic. Ionic bonds occur between ions, atoms which have become either negatively or positively charged when their number of electrons are no longer equal to their number of protons. Atoms in such bonds can be considered polar, but only at...

Test yourself: Is CH4polar or nonpolar? Hint: Draw out the molecular shape, and then calculate the electronegativity difference. Answer: Since all the dipole moments cancel in this tetrahedral molecule, CH4is nonpolar. References LibreTexts: 6.1: Electronegativity and Polarity ...
Thus, CO2is a nonpolar molecule. Test yourself: Is CH4polar or nonpolar? Hint: Draw out the molecular shape, and then calculate the electronegativity difference. Answer: Since all the dipole moments cancel in this tetrahedral molecule, CH4is nonpolar. ...

For the two diether systems, anionsare found in locations from which they are excluded in the alkyl-substitutedsystems. This removes the longer range (polar/nonpolar) pattern ofalternation that gives rise to the prepeak in alkyl-substituted systems.EBSCO_AspJournal of Physical Chemistry B...
