Answer: No, a t high pressures, volume of a real gas does not compare with the volume of an ideal gas under the same conditions.

Reason:

For an ideal gas, there should not be any intermolecular forces of interaction. However, for real gases there are intermolecular forces of interaction like dipole-dipole and dipole-induced dipole. Further, at high pressures, molecules are close by. Hence, extend of these intermolecular forces is expected to be high. This results in decreases in volume of real gas. Thus, volume of a real gas does not compare with the volume of an ideal gas under the same conditions.
