Detailed explanation-1: -Explanation: London dispersion forces occur between nonpolar molecules and are extremely weak. Dipole-dipole forces are between polar molecules, and since polar molecules have slight charges, their force is more similar to ions, giving them a moderately strong bond.
Detailed explanation-2: -London dispersion forces result from the coulombic interactions between instantaneous dipoles. Dispersion forces are present between all molecules (and atoms) and are typically greater for heavier, more polarizable molecules and molecules with larger surface areas.
Detailed explanation-3: -All molecules, whether polar or nonpolar, are attracted to one another by London dispersion forces in addition to any other attractive forces that may be present.
Detailed explanation-4: -Put in order from strongest to weakest: London Dispersion Forces, Hydrogen Bonds, Dipole-dipole interactions, ionic bonding, and covalent bonding.
