what type of intermolecular attraction is of variable strength? there may be more than one correct answer…

Brief Explanations:

London dispersion forces vary based on molecular size and polarizability. Dipole - dipole attractions vary with the magnitude of the dipole moment. Hydrogen bonding strength varies depending on the electronegativity of the atom bonded to hydrogen and the environment. Ionic, metallic, and network covalent bonding have more fixed - strength characteristics within a particular compound or material.

Answer:

A. London dispersion forces, B. Dipole - dipole attraction, C. Hydrogen bonding
