Maximum deviation from ideal gas is expected from:
NH3(g)
H2(g)
N2(g)
CH4(g)
Deviation from the ideal behavior is because of the attraction between the gas particles. As ideal gases have no interaction between them hence are called ideal. are nonpolar gases having weak London dispersion forces and show less deviation from ideal behavior while
is polar in nature and show maximum deviation from ideal behavior.
Hence Option 1 is correct
