Dipole arrows
One of the sapling questions suggested using dipole arrows to solve it. I solved it without them, but how could we use dipole arrows? What do they show?

Re: Dipole arrows
Dipole arrows represent the dipole moment in a molecule. The arrow points towards the more electronegative atom. For example, water has an arrow pointing towards the oxygen in between the hydrogens representing the net dipole moment.

Re: Dipole arrows
The arrow represents the dipole moment and it goes from positive to negative (pointing towards the negative end of the bond).

Re: Dipole arrows
Dipole arrows will point towards the end which has higher electronegativity. For that question we had to consider how the different dipole forces would create a net dipole force, and in which direction.

Re: Dipole arrows
Dipole Arrows are simply the vectors we draw on the structure of a molecule from the slightly positive charged element to the slightly negative element. if these arrows are equal in magnitude and opposite in direction, then they cancel out rendering the molecule nonpolar.

Re: Dipole arrows
Dipole arrows point towards the atom with partial negative charge and more electronegativity and points away from the atom with partial positive charge and less electronegativity. We can use these to solve problems when drawing things out by cancelling out arrows of dipole moments pointing in opposite directions, indicating a nonpolar structure. If the arrows don't cancel out and point in the same direction, this could indicate a polar structure. Revist Dr. Lavelle's example in Friday's lecture about cisplatin.

Re: Dipole arrows
The arrows will point to the more electronegative element, and will occur when there is a dipole moment.

Re: Dipole arrows
Dipole arrows show where the electrons have a high propensity to lie. They typically point to the most electronegative atom in the molecule. For example, in H2O the dipole arrows would point toward the oxygen atom.

Re: Dipole arrows
Dipole arrows signify that there is a dipole moment within the covalent molecule. Dipole arrows point towards the auto with the highest electronegativity in the structure.
