Web3 iun. 2015 · The boiling point of tetrahydropyran is 361 K while that of ethyl propyl ether is 337 K. The corresponding standard enthalpies of vaporization ($\Delta H^\circ_{\text{vap}}$) are 35 and 31 kJ/mol. This is consistent with the higher dipole moment of cyclic structures mentioned in @ron's answer. WebIt looks like you might have flipped the two concepts. Branching of carbon compounds have lower boiling points. An example of this would be neopentane - C(CH3)4 - which has a boiling point of 282.5 Kelvin and pentane - CH3CH2CH2CH2CH3 - which has a boiling point of 309 Kelvin. Pentane has the straight structure of course.
