A 0.2 molar solution of a solute,X,in benzene,displays an osmotic pressure given by the formula $\pi$ = (0.1)RT.Which of the following is most likely to be the case? A)X exists in benzene as X. B)X exists in benzene as X₂. C)X exists in benzene dissociated into two particles. D)This solution strongly deviates from ideal behavior. E)None of these is plausible.

The osmotic pressure is half of what would be expected for a 0.2 molar solution, suggesting that the solute exists as dimers (X₂) in benzene, effectively reducing the number of particles contributing to osmotic pressure.
