Dispersion forces

[Jolene Robles 2H]

Hello,

How do you arrange molecules from strongest London dispersion forces to weakest London dispersion? An example for this question on question 18 on the achieve homework for weeks 5/6.

[Donovan McGraw 2C]

Larger molecules have stronger London Dispersion Forces. Using the atomic radius trend will be able to help you out with this one. Larger atoms are located to the left and downwards on the periodic table.

[Luke_Dreyer 2F]

Larger molecules have larger london dispersion forces, so atoms going down and to the left will have a stronger london dispersion force. Similarly, if one molecule has a greater number of atoms in it that increases the mass which in turn increases the london dispersion force.
