What gas is more ideal N2 or HBr and why?

Answer 1

Hydrogen and neon are similar in their behavior as nearly ideal gasses.

Normally, deviations from ideal gas behavior become prominent as the temperature approaches the condensation (or equivalently boiling) point. Real gasses condense because of the attractive forces between the atoms and an ideal gas has no inter atomic forces.

Neon condenses at 27 degrees Kelvin and hydrogen condenses at 20 degrees Kelvin.

One expects neon to show more deviation from ideal gas behavior.

Answer 2

N2 is non polar so weak vander woals forces present between molecules.HBR is polar so strong dipole-dipole forces present.Hence Ideal gases have no inter molecular forces,the gas with less inter molecular force behaves idealy.

Answer 3

Nitrogen gas (N2) is more ideal than hydrogen bromide (HBr) because nitrogen is a diatomic molecule with a smaller molar mass and does not dissociate into ions like HBr does. This results in N2 following the ideal gas behavior more closely, as it has fewer intermolecular interactions.

Answer 4

HBr because it's a dipole, which increases the force of attraction between the molecules.

Answer 5

Neon (Ne), as it has no dipole moment.
