SF₆ is the gas, that is most likely to depart from the assumption of the kinetic-molecular theory that says there are no attractive or repulsive forces between molecules.
What is Kinetic- molecular theory?
The assumption that matter is made up of microscopic particles that are always in motion forms the foundation of the kinetic-molecular theory, which explains the states of matter. The observable characteristics and behaviours of solids, liquids, and gases are explained by this theory. The theory specifically pertains to the ideal gas model of a gas. An ideal gas is a hypothetical gas whose behaviour exactly matches all of the kinetic-molecular theory's presumptions.
What are molecules?
The smallest component of a substance possesses both its chemical and physical characteristics. One or more atoms make up molecules. They may have the same atoms or different atoms if they have more than one (a water molecule has two hydrogen atoms and one oxygen atom).
Hence, SF₆ is the gas, that is most likely to depart from the assumption of the kinetic-molecular theory.
