Question

Maximum deviation from ideal gas is expected from:

• A. $H_2\left(g\right)$
• B. $N_2\left(g\right)$
• C. $C{H}_4\left(g\right)$
• D. $N{H}_3\left(g\right)$

Answer 1

The correct option is D $N{H}_3\left(g\right)$

The deviations from ideal gas depend on the temperature and pressure considered. Considering the given 4 options (hydrogen, ammonia, methane and nitrogen), AMMONIA is the one which shows bigger deviation under the same conditions.NH3 will show maximum deviation from ideal gas due more to dipole -dipole attractions which leads to more attractive forces between molecules of $N{H}_3$.

Hence option D is correct.
