Verified step by step guidance1
Identify the types of intermolecular forces that can exist between molecules. The main types are London dispersion forces, dipole-dipole interactions, and hydrogen bonding.
Recognize that water (H_2O) is a polar molecule because of the difference in electronegativity between hydrogen and oxygen and its bent molecular shape, which creates a permanent dipole moment.
Understand that because water is polar, dipole-dipole interactions occur between the positive end (hydrogen) of one molecule and the negative end (oxygen) of another molecule.
Note that water molecules contain hydrogen atoms bonded directly to a highly electronegative atom (oxygen), which allows for hydrogen bonding, a special and stronger type of dipole-dipole interaction.
Remember that all molecules, including water, exhibit London dispersion forces due to temporary fluctuations in electron density, so these forces are also present alongside dipole-dipole and hydrogen bonding.
