Which of the following van der waals forces would have the most action among molecules of methane. ch4 a. diapole-diapole b. ion-diapole c. hydrogen-diapole d. london dispersion

- d. London dispersion

Explanations:- Dipole-dipole forces of attraction are present in polar covalent molecules. methane is not a polar molecule so the option is not correct.

Ion-dipole forces are present in ionic compounds. Methane is not an ionic compound so second option is also not correct.

Hydrogen bond is present in polar covalent molecules in which hydrogen is bonded to more electron negative(N, O or F)atom. So, third option is also not correct as the hydrogen is bonded to less electron negative carbon atom.

Methane is a non polar molecule and non polar molecules have weakest dispersion forces that are known as London dispersion forces.

So, the fourth option, d. London dispersion is the correct one.
