What are some non ideal gases?

Increasing the amount of intermolecular forces causes more deviations from ideality, so gases that have a larger molar mass would be less ideal that gases with a lower molar mass. (E.g. CO2 would be less ideal than He)

all gases interact with each other in the real world making them non-ideal. But some are very close to a ideal which makes the ideal gas law a good approximation.

Most gases are non ideal. Any gas that has intermolecular forces and take up volume are non ideal.

Pretty much all gases are not ideal. an "ideal gas" is just a concept to help us be able to solve problems and equations assuming that the gas does not take up any volume or have any intermolecular forces (which non-ideal gases obviously do).

Almost all gases that you use in an experiment would be non-ideal, but it is easier to do calculations with ideal gases.

ideal gases are for the purpose of creating a problem, gases are usually non ideal

Any gas that exhibits intermolecular forces and takes up volume.

Most gases are non ideal. Ideal gases are used to make it easy to calculate properties of gases using the ideal gas law (PV = nRT) as long as the pressure isn't too high or the temperature isn't too low or else that will cause deviations in the calculations.
