Answer #1

Highest vapour pressure is for substance which has weakest intermolecular force.

CO is polar. It will have dipole-dipole interaction.

N2 is polar. It will have dispersion forces.

I2 is polar. It will have dispersion forces.

H2S is polar. It will have dipole-dipole interaction.

HCl is polar. It will have dipole-dipole interaction.

Dispersion forces are weaker.

Between N2 and I2, N2 would have weaker dispersion forces because of its low molar mass.

So, N2 will have highest vapour pressure.

Answer: N2
