Web12. aug 2024 · Dipole-dipole forces are probably the simplest to understand. You probably already know that in an ionic solid like NaCl, the solid is held together by Coulomb attractions between the oppositely-charges ions. The Na + and Cl - ions alternate so the Coulomb forces are attractive. WebThe work done to rotate the dipole from θ = 0º to 90º is equal to the potential energy difference between these two configurations. W= ∆U =U (90º)−U (0º) From the equation (1.51), we write U = − pE cosθ, Next we calculate the work done to rotate one water molecule from θ = 0º to 90º. For one water molecule W = −pE cos 90º + pE cos0º = pE goodwill stores in chicago
