Boiling Point and IMFs

[Erika Patel 3I]

How would you determine the order of boiling temperatures for N2, O2 and NO since all of these compounds are linear and only experience LDFs?

[Luke_Dreyer 2F]

First, both O2 and N2 are nonpolar molecules, whereas NO is a polar molecule so it will experience dipole dipole forces that O2 and N2 don't so it will have the highest boiling point. O2 has a larger mass than N2 which means it will have a stronger london dispersion force than N2 so the order is NO>O2>N2.

[Damian Valle Garcia 3I]

Hello, not all of the molecules just have Ldf. NO experiences a dipole dipole attraction due to the difference in electronegativety. When comparing the other two, N2 and )2, you want to consider whic has the largest mass which means it will have a larger LDF.
