Which of the following gases would be most likely to experience ideal behavior at high pressures?

Answer 1

Which of the following gases would be most likely to experience ideal behavior at high pressures? 
a. F2 
b. Ne 
c. C2H6 

Yes. The answer is (b) Ne (Neon). This is because monoatomic gases such as neon do not experience intermolecular attractions and thus most likely to be close to ideal gases behavior. Not only that, Neon is a noble gas and is unreactive.
