Chemistry confusion about hydrogen bonding?

Summary - Boiling point, solubility, and surface tension of water are all based on interactions between water molecules - hydrogen bonding plays a part. Color and chemical reactivity are part of the bonds between atoms in the molecule - not related to hydrogen bonding.

Hello,

I will gladly try to clarify your confusion.

Boiling point, increased solubility, and surface tension are all processes that involve the water molecules' interaction with each other, intermolecular forces that are affected by hydrogen bonding. Hydrogen bonding is the strong interaction between hydrogen and nitrogen/oxygen/fluorine atoms on certain molecules - water is one of them. Hydrogen bonding in water attaches water molecules closer to each other and prevents boiling at lower temperatures, "encourages" other particles to be surrounded with water molecules in solution, and the water beads up better for surface tension and doesn't let forces break through immediately. These are all interactions which water molecules have with each other.

Color and chemical reactivity are based on the nature of the bonds within the water molecules. The O-H bond vibrates at a certain frequency, and this causes a certain frequency of color to be absorbed - this is the color we see. Chemical reactivity is based on how much energy it takes to break the O-H bond. Hydrogen bonding is not based on the actual bond, but by the atom's surface ineractions. <<
