Occurs when hydrogen bonded to F, O, or N, strength increases as electronegativity does
London Dispersion Forces (LDFs)
Grow larger as moles (# of electrons) increases, can become extremely strong for large molecules, present in every molecules but most of time weakest (expect in big molecules) so overpowered by stronger IMFs
Dipole-dipole
Occurs between 2 dipoles and is permanent medium strength which increases as electronegativity difference increases
Ion-dipole
Occurs between an ion and nearby polar molecule, stronger than dipole/dipole and hydrogen bc of full charge, strength increases as charge increases and molecule size increases
Dipole-induce-dipole forces
Occurs between permanent dipole (or ion) and nonpolar molecule
