Understanding Molecular Polarity and Interactions

Your chemistry grade depends entirely on knowing that molecules have relationship issues.

Polarity is basically just unequal sharing of electrons. If a molecule is asymmetrical,

it’s polar, which means it has a positive and negative side. This is exactly

why water is so sticky. It uses hydrogen bonds, the strongest intermolecular

force, to hold itself together like glue. That is literally the only reason

water takes so much energy to boil. Also, stop confusing Polarity with Molarity.

Molarity is just math for concentration. Just remember that like dissolves like. If you mix polar

and nonpolar, they separate faster than a bad breakup.
