Q. Which gas shows the least deviation from ideal behavior at room temperature and pressure?
कौन सी गैस कमरे के तापमान और दबाव पर आदर्श व्यवहार से सबसे कम विचलन दिखाती है?
Explanation
Ideal gas behavior is favored by:
- Small molecular size
- Weak intermolecular forces
- High temperature
- Low pressure
Comparing the options:
- H₂: Very small, weak van der Waals forces ✓
- CO₂: Larger, stronger intermolecular forces
- NH₃: Hydrogen bonding, highly polar
- C₄H₁₀: Large hydrocarbon, significant van der Waals forces
H₂ shows minimal deviation due to its small size and weak intermolecular interactions.
