What is hydrogen bonding and how does it affect water?

Answer 1

The cohesive forces in water resulting from hydrogen bonds cause the molecules at the surface of the water to be pulled downward into the liquid. As a result, water acts as if it has a thin "skin" on it's surface. You can observe water's surface tension by slightly overfilling a drinking glass with water. The water will appear to bulge over the rim of the glass.

Answer 2

Hydrogen atoms in water molecules will be attracted to the oxygens in other atoms because water is a polar molecule, this will cause water molecules to be attracted to each other and this causes tension on the surface of the water.

Answer 3

Water is probably the best and most common example of hydrogen bonding, and it explains many of water's properties. First of all, water is a strongly polar molecule. Oxygen's unpaired electrons means the 2 hydrogens bond at an angle, causing the molecule to have a positive end (where the hydrogens are) and a negative end (where the electrons are that aren't tied up in the bonds.) In a sample of water, the positive end of one water molecule will be somewhat attracted to the negative end of another water molecule. This is similar to dipole interaction, but considerably stronger. This inter-molecular attraction causes water to have surface tension, which is why water forms spherical droplets, expands when it freezes, forms 6-sided snowflakes, and more.
