The boiling point of cyclohexane at standard pressure  1 atm  is 80.74C  353.89 K . In comparison, the boiling point of n-hexane at the same pressure is 68.73C  341.88 K .The difference in boiling points can be attributed to the molecular structure and intermolecular forces present in both compounds. Cyclohexane is a cyclic compound, while n-hexane is a linear compound. Both compounds are nonpolar and exhibit London dispersion forces  van der Waals forces  as the primary intermolecular force.In general, larger molecules with more electrons have stronger London dispersion forces. Although both cyclohexane and n-hexane have the same molecular formula  C6H12  and the same number of electrons, the cyclic structure of cyclohexane allows its molecules to pack more closely together. This results in stronger London dispersion forces between the molecules, which in turn requires more energy to overcome, leading to a higher boiling point for cyclohexane compared to n-hexane.
