Due to differences in electronegativities molecules can have partial positive (δ⁺) or partial negative (δ^-) charges on individual atoms/portions.

Polarity of molecules

Typically in a polar covalent bond the more electronegative atom will be partial negative

Where to place it?

Why are they important?

The placement of these partial charges effects how molecules can interact with each other, magnetic fields, and different solvents.

On the next slide Click on "Two Atoms", then set up the molecule to look like this.

​​Step 1

When you're ready turn on the electric field and make note of what happens to the molecule.

​​Step 2

On the next slide Click on "Three Atoms", then set up the molecule to look like this.
