Symmetrical molecules, like BF3 can have bond dipoles, but they may either cancel or all point in one direction. No net dipole = nonpolar No net dipole = nonpolar 9-8 Hybridization When chemists measure the bond lengths and strengths of the 4 C – H bonds in CH4, the bonds are equivale...

ODYSSEY Polar Bonds and Molecules takes an entirely visual approach to distinguishing between nonpolar, polar covalent, and ionic compounds. Quantum chemical calculations are employed to present electron density distributions for more than thirty systems. The distributions are also available as color-coded...

Examples of Polar Molecules Water(H2O) is a polar molecule. The bonds between hydrogen and oxygen are distributed so that the hydrogen atoms are both on one side of the oxygen atom rather than evenly spaced. The oxygen side of the molecule has a slight negative charge, while the side with...
Why do some (but not all) molecules have dipole moments? If a molecule has polar bonds, does that mean it is a polar molecule? ODYSSEY Polar Bonds and Molecules takes an entirely visual approach to distinguishing between nonpolar, polar covalent, and ionic compounds. Quantum chemical ...
Mixed-dimensional systemspolaronmolecularWe address the problem of a single impurity atom moving in a two-dimensional (2D) layer immersed in a 3D Fermi gas. Using a variational approach, we show that in this mixed-dimensional (MD) system, there is a transition between polaron and molecule ...
