Which of the following interactions are present between CO2 molecules?

Question

1)london forces 2)ion-dipole forces 3)dipole-dipole attration

I am so confused I don't know what these terms means my book doesn't explain it well How would I know if CO2 is only london forces I don't know anything about symmetrical or any terms please explain in easy way

Answer 1

As CO2 is non polar since the molecule is linear and symmetric, you have only london forces which are forces existing in all types of molecules

This are temporally dipoles as explained in the link

Answer 2

London dispersion forces are the strongest intermolecular forces for CO2.

Dispersion forces are the only type of intermolecular force operating between non-polar molecules, which CO2 is an example of.

::O=C=O::  Notice that CO2 is a linear molecule, thus making it non-polar.

CO2 isn't an ion, so it cannot be ion-dipole and dipole-dipole interactions are only for polar molecules, which CO2 isn't.
