The intermolecular forces are responsible for: holding molecules close together. Identify the strongest intermolecular force present in each substance. For example, a cation is a positively charged ion and so would be attracted to the negative portion of a molecule while being repelled by the positive portion. hydrogen bonding. Intramolecular forces (bonding forces) exist within molecules and influence the chemical properties. (strongest) 2. Larger molecules will have stronger London dispersion forces. O A. ionic bonding B. dipole-dipole forces C. polar covalent bonding OD. These forces are responsible for the formation of chemical bonds.
