Solution
The correct option is D 3,4
The statements 3 and 4 are incorrect about the real gases.
1. The molecules of real gas attract each other. The molecules of ideal gas do not attract each other as there are no forces of attraction or repulsion between ideal gas molecules.
2. They show deviation from Boyle's and Charles' law. The real gases obey the van der Waals equation but they do not obey ideal gas equation.
3. Volume of gas molecules are not negligible. The volume of real gas molecules cannot be neglected in comparison to the volume of the container.
4. The molecules have some mass.
