Explanation / Answer

18) a. london forces (this force is present between the atoms or molecules , this force is caused by the fluctuation in the electron distribution with in the molecules or atoms)

19) b. dipole-dipole forces (dipole-dipole forces are exists in all molecules which are polar.polar molecules have permanent dipoles which interact with the permanent dipoles of neighbouring molecules.The positive end dipole is attached to the negative end dipole, this attraction is called dipole-dipole attraction)

20) a. london forces (this force is present between the atoms or molecules , this force is caused by the fluctuation in the electron distribution with in the molecules or atoms)
