Which gas deviates most from ideal behavior at the same conditions?
A.NH₃
B.He
C.Ne
D.H₂
Explanation
Core Concept
Ammonia is polar with strong hydrogen bonding, so its intermolecular attractions are large, and its bigger electron cloud adds dispersion forces. Both effects pull real pressure below the ideal prediction.
Correct Answer
ANH₃
