# The slight negative charge at one end of one water molecule is attracted to the sight positive charge of another water molecule. What is this attraction called?

This is called $\text{hydrogen bonding}$, and it is a potent intermolecular force.
We could represent this phenomenon as, ""^(delta+)H-O^(delta-)-H^(delta+) (of course the molecule is bent). The hydrogen termini are thus partially positive, and they tend to align with the partially negative oxygen atoms on adjacent molecules. In aggregate, this is a potent intermolecular force, which also operates in water-like solvents such as $N {H}_{3}$ and $H F$.
