(c) an aqueous solution of CO2 exhibits dipole-dipole forces between solute and solvent

Explanation:

Co2 is a non-polar molecule.

It is actually shown to be O=C=O.

When dissolved in water to get aqueous solution.

Dipole on water molecule can induce dipole on CO2.

This entails that we should have dipole-induced dipole forces when we have a mixture or solvent and solute.

But the given statement states dipole dipole forces between solute and solvent.

Hence the statement is false.
