the main type of attractive forces between molecules of water (h₂o) are,
dispersion forces
polar covalent
dipole - dipole attractions
ionic bonds
hydrogen bonds

Explanation:

• Dispersion forces are weak forces present in all molecules but are not the main force in water.
• Polar covalent is a type of bond within a molecule (between H and O in \(H_2O\)), not an intermolecular force.
• Dipole - dipole attractions are present in polar molecules, but hydrogen bonds are stronger in water due to the highly electronegative O atom and H atoms attached to it.
• Ionic bonds are between ions (not in \(H_2O\) molecules).
• Hydrogen bonds form between the O of one \(H_2O\) molecule and the H of another \(H_2O\) molecule. They are a special type of dipole - dipole interaction and are the main intermolecular attractive forces in water.

Answer:

hydrogen bonds
