Which statement is true?
Intermolecular forces occur between atoms in a molecule and depend on the polarity of the atoms involved.
Intermolecular forces only occur between molecules of different types and depend on the molarity of the molecules involved.
Intermolecular forces usually occur between molecules of the same type and depend on the polarity of the molecules.
Intermolecular forces occur between atoms in a molecule and depend on the molarity of the atoms involved.
A molecule of HCl contains polar covalent bonds and displays dipole-dipole interactions when it encounters other HCl molecules. Which of these two forces is stronger?
Polar covalent, because it is an intermolecular force.
Polar covalent, because it is an intramolecular force.
Dipole-dipole, because it is an intermolecular force.
Dipole-dipole, because it is an intramolecular force.
