1.) Define the following. Hydrogen bonds. A.) The force between polar molecules when the opposite partial charges of a molecule exert a force on each other.

B.) Forces created by temporary dipoles that result from the movement of electrons in non-polar molecules.

C.) A force created by differences in electronegativity and the large size of the hydrogen atom make them especially strong.

D.) A force created by similarities in electronegativity and the small size of the hydrogen atom make them especially strong.

E.) A force created by differences in electronegativity and the small size of the hydrogen atom make them especially strong.
