Final answer:
A hydrogen bond forms between the weakly positive charge on the hydrogen atoms of one water molecule and the weakly negative charge on the oxygen atoms of another water molecule. It is a relatively weak but important type of dipole-dipole interaction in water.
Step-by-step explanation:
The bond between water molecules is called a hydrogen bond.
A hydrogen bond forms between the weakly positive charge on the hydrogen atoms of one water molecule and the weakly negative charge on the oxygen atoms of another water molecule. It is a relatively weak but important type of dipole-dipole interaction in water.
Hydrogen bonding in water affects its properties, such as its high boiling and melting points, high surface tension, and cohesion.
