Answer
We can tell from Table 11.6 that Neon has much weaker intermolecular forces.
Work Step by Step
The critical temperature of Neon is much lower (about 45 Kelvin) than the critical temperature of Argon (150.9 Kelvin). As the book italicizes on page 461, the greater the intermolecular forces, the higher the critical temperature of the substance will be. This makes sense, for when a substance changes phases (for instance, from liquid to gas), intermolecular forces are being broken. Consequently, if the critical temperature for Argon is higher, that means that it takes more energy to break the intermolecular forces, indicating that Argon has stronger intermolecular forces than Neon.
