Polar Molecules Electrons in a covalent bond are not shared evenly (+) (-) (+) Polar Covalent - Water Molecule Polar Molecules (like water) Poles = opposite ends of something Molecules can have “poles”: Positive Pole vs. Negative Pole Polar Molecules (like water) Polar molecules have slight, partial charges at either end. One end is slightly negative The other end is slightly positive Caused by the uneven sharing of electrons in a covalent bond Water: Structural Formula (-) O H H (+) (+) Hydrogen Bonds (H-bonds) Attraction between the slightly negative and slightly positive sides of polar molecules Not a true chemical bond (does not create new molecules) A relatively weak force (Easily broken) Most common example = water Hydrogen Bonds and Water H-bonds
