Question

how does this force affect the phase of substances?
on the previous screen, you determined that the strength of the london dispersion forces from weakest to strongest was:
chlorine, bromine, iodine.
why do you think that is? select all that apply:
the larger the molecule, the larger the electron cloud. the larger the electron cloud, the more it can be distorted.
the color of the molecules contributes to the forces.
the larger the molecule, the stronger the london dispersion forces.
the smaller the electron cloud, the more it can be distorted
phase: all gas mostly liquid mostly solid
molar mass (g/mol): 70.906 159.808 253.809
three halogens are shown at room temperature. chlorine is a gas, bromine is a liquid that evaporates readily, and iodine is a solid that easily sublimes (goes from solid to gas).

Explanation:

London dispersion forces are a type of intermolecular force. The strength of London dispersion forces depends on the size of the electron cloud. Larger molecules have larger electron clouds. Larger electron clouds can be more easily distorted, which leads to stronger London dispersion forces. The color of the molecules has no relation to the strength of London dispersion forces. Smaller electron clouds are less easily distorted.

Answer:

The larger the molecule, the larger the electron cloud. The larger the electron cloud, the more it can be distorted.
The larger the molecule, the stronger the London dispersion forces.
